The 2 in the formula AgS is a
1. coeffcient
2. subscript
3. superscript
4. binomial​

Answers

Answer 1

Answer:

Subscript, or B

Explanation:

AgS is the equation for the chemic reaction of Silver + Sulfur, since the subscript of 2 goes by the g in the equation, this would equal subscript.

Remember subscripts are located at the BOTTOM of a coefficient and superscripts are located at the TOP of a coefficient.

Related Questions

The valences of metal x,y and z are 1,2 and 3 respectively. What are the formulae of their;a) hydroxides, b) sulphates, c) hydrogen, d) carbonates, e) nitrates, f) phosphates

Answers

Answer:

See answer below

Explanation:

AS we know that the valence for those metals X, Y, and Z are 1, 2 and 3, we can determine the formula of each compound.

1. Hydroxides.

An hydroxide is formed when an oxyde of a metal reacts with water. When this happens, the general molecular formula is:

Meₐ(OH)ₙ

Where:

a: valence or charge of the hydroxide (Which is -1)

n: valence of the metal.

Following this, the formula for X, Y and Z would be:

XOH

Y(OH)₂

Z(OH)₃

2. Sulphates

Sulphates follow a similar rule of hydroxide in the general molecular formula, but instead of having a charge of -1, it has a charge of -2 so:

Mₐ(SO₄)ₙ

So, following the rule:

X₂SO₄

Y₂(SO₄)₂ ------> YSO₄

Z₂(SO₄)₃

3. Hydrogens

Following the same rule as the previous, hydrogens works with a charge of -1, so:

MₐHₙ

Then:

XH

YH₂

ZH₃

4. Carbonates.

This follows the same rule as sulphates, with the same charge so:

Mₐ(CO₃)ₙ

Then:

X₂CO₃

YCO₃

Z₂(CO₃)₃

5. Nitrates

Follow the same rule as the hydroxides, with the same charge of -1.

Mₐ(NO₃)ₙ

Then:

XNO₃

Y(NO₃)₂

Z(NO₃)₂

6. Phosphates

In the case of phosphates, these have a charge of -3 so:

Mₐ(PO₄)ₙ

Then:

X₃PO₄

Y₃(PO₄)₂

Z₃(PO₄)₃ ----> ZPO₄

Hope this helps

Its is the change in energyof a neutral atom when an electron to the atom to form negativeion, thus neutral atom gain electon.What property of element is being described

Answers

Answer:

Electron affinity.

Explanation:

An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such determines or defines the structure of a chemical element.

Generally, atoms are typically made up of three distinct particles and these are protons, neutrons and electrons.

Electron affinity can be defined as the ability of an atom of a chemical element to accept or accommodate an electron.

This ultimately implies that, electron affinity is the change in energy of a neutral atom of a chemical element when an electron is added to the atom to form negative ion, thus, a neutral atom gain electron.

In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.

Consider an ideal gas contained in a cylinder with the volume 34.4L, temperature 667K and pressure 2atm.What will be pressure of the gas if it is heated at 1000k and the volume becomes 50L.

Answers

Given :

An ideal gas contained in a cylinder with the volume 34.4L, temperature 667K and pressure 2 atm.

To Find :

What will be pressure of the gas if it is heated at 1000k and the volume becomes 50L.

Solution :

We know, by ideal gas equation :

[tex]Pv = nRT[/tex]

Now, in the given question only their are two state and also their is no leakage so amount of gas is also constant.

So,

[tex]\dfrac{P_1V_1}{T_1} = \dfrac{P_2V_2}{T_2}\\\\\dfrac{2\times 34.4}{667} = \dfrac{P_2 \times 50}{1000}\\\\P_2 = \dfrac{2\times 34.4 \times 1000}{667 \times 50}\ atm\\\\P_2 = 2.06 \ atm[/tex]

Therefore, the pressure of gas is 2.06 atm.

A rocket launches because of __________.
A. an opposite reaction
B. it's large mass
C. its gravity
D. air resistance

Answers

Answer:

an opposite reaction

Earth's gravity is still pulling down on the rocket. When a rocket burns propellants and pushes out exhaust, that creates an upward force called thrust. To launch, the rocket needs enough propellants so that the thrust pushing the rocket up is greater than the force of gravity pulling the rocket down.

Answers

Answer:

a. absorbs energy as heat and has positive enthalpy of solution.

Explanation:

A reaction can either be exothermic or endothermic. An endothermic reaction, as the dissolution described in the question, is that which absorbs heat energy from the surroundings in order to start the reaction.

Because an endothermic reaction makes heat lost from the surroundings, the enthalpy (∆H) of the solution will be positive (+). ∆H is got by finding the difference between the enthalpy of the reactants and products and since the enthalpy of a product in endothermic reaction is more, the enthalpy change (∆T) will be positive.

How many grams would be in 1.752 x10^26 formula units of Ca(No3)2

Answers

Answer:

47730 grams.

Explanation:

First we convert 1.752x10²⁶ formula units of Ca(NO₃)₂ into moles, using Avogadro's number:

1.752x10²⁶ formula units ÷ 6.023x10²³ formula units/mol = 290.88 mol

Then we convert 290.88 moles of Ca(NO₃)₂ into grams, using the molar mass of Ca(NO₃)₂:

290.88 mol * 164.088 g/mol = 47730 g

Many people try to eliminate fat from their diets. Which is one reason it is
necessary for humans to eat fat?

Answers

Answer:

C

Explanation:

While it is common to notice that many people avoid food that contain fat due to the fact that they are avoiding the adverse implications of fat consumption, the consumption of fat also has some advantages.

Prominent among the advantages of fat in the body is that fat cushions the internal organs. This cushioning of the internal organs avoids sudden damage to these organs.

For this reason, it is necessary for humans to eat fat.

a concentrated solution of sulfuric acid, H2SO4, has a concentration of 18.0 M. How many mL of the concentrated acid would be required to make 250. mL of a 1.00 MH2SO4 solution?

Answers

Answer: A 13.88 mL of the concentrated acid would be required to make 250. mL of a 1.00 M [tex]H_{2}SO_{4}[/tex] solution.

Explanation:

Given: [tex]M_{1}[/tex] = 18.0 M,     [tex]V_{1}[/tex] = ?

[tex]M_{2}[/tex] = 1.00 M,         [tex]V_{2}[/tex] = 250 mL

Formula used to calculate the volume of concentrated acid is as follows.

[tex]M_{1}V_{1} = M_{2}V_{2}[/tex]

Substitute the values into above formula as follows.

[tex]M_{1}V_{1} = M_{2}V_{2}\\18.0 M \times V_{1} = 1.00 M \times 250 mL\\V_{1} = \frac{1.00 M \times 250 mL}{18.0 M}\\= 13.88 mL[/tex]

Thus, we can conclude that 13.88 mL of the concentrated acid would be required to make 250. mL of a 1.00 M [tex]H_{2}SO_{4}[/tex] solution.

At a high concentration do you have more or less particles per unit volume

Answers

Answer:

More particles per unit volume

Explanation:

Concentration means the amount of solute in a solution. Now, the amount of solute also means the number of particles of solute present in a solution.

Hence, when we use the term "high concentration", we imply that the amount of solute present or the number of particles present in a solution is high.

Thus, at high concentration, there are more solute particles than solvent particles in a solution.

74g of Ca(OH)2 (74 g/mol) in 340 ml solution

Answers

Answer:

This question is asking to calculate the molarity of the solution based on the information provided.

The answer is 2.94M

Explanation:

Molarity of Ca(OH)2 solution = number of moles (n) ÷ volume (V)

Using the formula below to calculate number of moles of Ca(OH)2.

mole = mass/molar mass

Molar mass of Ca(OH)2 = 74 g/mol

mole = 74g/74g/mol

mole = 1mol

Volume of Ca(OH)2 solution = 340ml = 340/1000 = 0.340 L

Molarity = 1/0.340

Molarity = 2.94M
