Carbon dioxide, when present in sufficient amounts, will bind with water to form ____________ , which is capable of dissociating into bicarbonate and hydrogen ions.

Answer:

Chlorine is a halogen and sodium is an alkali metal.

Explanation:

A solution of the ionic salt Lihco3 would have 11.3 pH.

In chemistry, salt exists as a chemical compound consisting of an ionic group of positively charged cations and negatively charged anions, which results in a combination with no net electric charge. A common example stands table salt, with positively charged sodium ions and negatively charged chloride ions.

The fragment ions in a salt compound can be either inorganic, such as chloride (Cl−), or organic, such as acetate (CH3CO−2). Each ion can be either monatomic, such as fluoride (F−), or polyatomic, such as sulfate (SO2−4).

Answer:

836 km

Explanation:

76*11=836

Answer:

836km

Explanation:

76km/hr = 76×1000÷3600= 190/9 m/s

11hours =39600 s

Distance=speed×time

Distance=190/9 × 39600= 836,000m

So distance is 836,000m or 836 km.

This method is possible only if body is moving linearly and the velocity is constant.

If there is uniform acceleration use Newton's laws of motion.

If is acceleration is varying then use calculus methods.

Answer:

The Law of Conservation of Mass states that the mass of the system must remain constant over time as the system's mass cannot change because energy is not created nor destroyed. To tell if a chemical equation meets this law, check to see if the number of atoms is the same on both sides of the chemical equation.

Remember, when counting the atoms in a equation the subscript is the number that represents the quantity of that specific atom. Subscripts are numbers that come after a symbol and below. If an element does not have a subscript, then it is understood that the subscript is 1.  The coefficent represents the quantity of molecules, the coefficient multiplies everything in the formula.

Answer:

Refer to the periodic table to do this.

Explanation:

1. Na, K, Cs Fr, Rb

  Sodium, Potassium, Cesium, Francium, Rubidium

  3, 4, 6, 7, 5

Ascending order: Na, K, Rb, Cs, Fr

2. Ca, Sr, Ba, Ra, Mg

   Calcium, Strontium, Barium, Radium, Magnesium

   4, 5, 6, 7, 3

Ascending Order: Mg, Ca, Sr, Ba, Ra

When doing the electronic configuration of the elements, count how many number of divides it has. For example, Na(Sodium) has 11 electrons and it is divided like this: 2,8,1. So it divides into 3 parts so there will 3 shells for sodium.

Heat required is mcΔT=100×0.39×50=1950 J

Solve any question of Thermodynamics with:-

The specific heat of the substance that requires 270 J of energy to raise the temperature is 2.57 J/g⁰C.

The specific heat capacity of the substance is calculated as follows;

Q = mcΔФ

where;

c = Q/mΔФ

c = (270) / (4.2 x 25)

c = 2.57 J/g⁰C

Thus, the specific heat of the substance that requires 270 J of energy to raise the temperature is 2.57 J/g⁰C.

Answer:

Helium is less dense. Because helium is lighter than air, a helium balloon rises, just as an air bubble rises in more dense water

Explanation:

Also why not. It just is.

Answer:

This is due to the fact that helium has a lower density. A helium balloon rises like an air bubble in more dense water because helium is lighter than air. Another gas lighter than air is hydrogen, which is even lighter than helium.

Explanation:

Answer:

Correct option is

D-1.0mol/dm³

Mass of NaOH (m) = 1g

The volume of water (V) = 250 ml

Mol. wt of NaOH (m) = 40g/mol

Molarity (M) =M×V(ml)m×1000

M=40×2501×1000

M=101 or 0.1 M

This problem is providing the ionic radius of an anion, A²⁻ as 0.290 nm and asks for that of the cation A²⁺ in comparison to the former.

Firstly, we need to recall the concept of ionic radius, as the distance between the nucleus and the outermost electron shell of an ion. In such a way, we can have two scenarios:

1. Anions result from the gain of electrons exhibited by a nonmetal, which means they turn out bigger than the neutral atom.

2. Cations result from the loss of electrons exhibited by a metal, which means they turn out smaller than the neutral atom.

With the aforementioned, we infer that the cation A²⁺, will me smaller than the anion A²⁻, which means it will have an ionic radius smaller than 0.290 nm.

Explanation:

DCO2/H2 = 44/2 = 22............................

Answer:

the balanced equation for the above reaction is as follows;

3NiCl₂ + 2K₃PO₄ ---> Ni₃(PO₄)₂ + 6KCl

stoichiometry of NiCl₂ to K₃PO₄ is 3:2

the number of NiCl₂ moles reacted - 0.0102 mol/L x 0.134 L = 0.00137 mol

according to molar ratio  

if 3 mol of NiCl₂ reacts with 2 mol of K₃PO₄

then 0.00137 mol of NiCl₂ reacts with - 2/3 x 0.00137 = 0.000911 mol of K₃PO₄

molarity of given K₃PO₄ solution - 0.205 M

there are 0.205 mol in 1000 mL  

therefore volume of 0.000911 mol - 0.000911 mol / 0.205 mol/L = 4.44 mL  

volume of K₃PO₄ needed is 4.44 mL

The carbon atoms are sp3 hybridized.
