Answer:

4.5moles

Explanation:

2.25moles times 2 hydrogen atoms per one molecule

The number of hydrogen atoms present in 2.25 moles of hydrogen carbonate is 4.5.

A mole of a compound is equivalent to the one formula unit of the compound. The number of atoms of each element in a mole of the compound can be given from the formula unit.

1 unit of hydrogen carbonate consists of 2 atoms of hydrogen. Thus, 1 mole of hydrogen carbonate has 2 hydrogen atoms.

The number of hydrogen atoms in 2.25 mole of hydrogen carbonate can be given as:

[tex]\rm 1\;mol\;H_2CO_3=2\;atoms\;Hydrogen\\2.25\;mol\;H_2CO_3=2.25\;\times\;2\;atoms\;of\;hydrogen\\2.25\;mol\;H_2CO_3=4.5\;atoms \;of\;Hydrogen[/tex]

The number of hydrogen atoms present in 2.25 moles of hydrogen carbonate is 4.5.

Answer:

3.2×10^-3 mol

Explanation:

The equation for molarity is M= n/L. Where "M" is Molarity, "n" is the number of moles of solute, and "L" is the total liters in solution.

The question gives you the volume in mL, so to convert "mL" to "L" you need to divide by 1000. (6.70mL/ 1000L)= 0.0067L.

Now you can plug the numbers into the equation. 0.480M= n/ 0.0067L), multiply (0.480M×0.0067L)= 0.003216 mol. The scientific notation is 3.2×10^-3, 10^-3 because you move the decimal back three times and 3.2 because there are 2 sig figs.

Answer:

C2H3

Explanation:

.

The empirical formula of the compound is C3H3.

In science, the exact equation of a synthetic compound is the most straightforward entire number proportion of particles present in a compound. A basic illustration of this idea is that the experimental recipe of sulfur monoxide, or somewhere in the vicinity, would just be Thus, similar to the observational recipe of di sulfur dioxide, S2O2.

In this manner, sulfur monoxide and di sulfur dioxide, the two mixtures of sulfur and oxygen, have a similar exact equation. Nonetheless, their sub-atomic equations, which express the quantity of iotas in every particle of a synthetic compound, are not something similar.

Explanation:

At 100℃,P=1atm

V=10L

At NTP, T=20

P=1atm

PV=nRT

PV=nRTV∝C

So at NTP temp is less than 100℃ and as the volume is proportional to temperature.

So at NTP temp is less than 100℃ and as the volume is proportional to temperature.Thus, the volume will be less than 10L as the temperature decreases.

Answer:

B)   n2=V2N1/V1

the second part is 0.080

Explanation:

EDGEEEEE

The volume and number of moles of a gas are in direct proportion. Hence, as the volume increases from 5 ml to 1 L, number of moles increases from 0.040 to 8 moles.

Avogadro's law, states that, at constant pressure and temperature, the number of moles of a gas is directly proportional to the volume of the gas. Hence,

V1/n1 = V2/n2, for two different volumes.

Given that, v1 = 5 ml

v2 = 1 L = 1000 ml

n1 = 0.040 mol

then n2 = v2 n1/ v2

Number of moles at 1 L = (0.040 mol × 1000 ml)/5 ml = 8 moles.

Hence, the number of moles of the gas added  = 8 - 0.040 = 7.96 moles.

Therefore, the amount of gas added at the increased volume is 7.96 moles.

          6.58g of Oxygen gas

Divide 6.58g by molar mass of oxygen (32g/mol)

6.58/32 = 0.205625 mol

Use mol to mol ratio from looking at the coefficients of the reactants, the mol ratio of Hydrogen gas to Oxygen gas is 2:1, so for every 1 mol of Oxygen, you need 2 times the mol of hydrogen for it to make water.

0.205625 * 2 = 0.41125 mol

To get the mass of hydrogen gas needed in the reaction, turn 0.41125 mol into mass by multiplying it with Hydrogen gas's molar mass, which is 2.02 g/mol.

0.41125 * 2.02  ≈ 0.83g of H2

The reproduction of hydra is through budding process from its body. This process of regeneration is called mitosis.Mitosis is a type of cell division process. Thus option A is correct.

Mitosis is a cell division process in which one cell produces two identical daughter cells. The term mitosis means the duplication of the genetic material chromosomes with the exact gene information.

Different stages in mitosis together is called mitotic phases. Hydra is an invertebrate freshwater organism. Hydra has a translucent tubular body which can be elongated and contracted.

Hydra is classified to the phylum hydrozoa. It have a regeneratable head. The reproduction of hydra is through budding. A small bud first projects from its tubular body which then develops and emerges out by cell division.

The divided daughter hydra will grow as a matured hydra. This overall budding process takes places through mitosis. Hence, option A is correct.
