I believe it is B... because all balance equation are supposed to follow the law of conservation of mass

Answer: The correct answer is Option B.

Explanation:

Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.

This also means that total mass on the reactant side must be equal to the total mass on the product side.

For the given chemical reaction:

$A+B+C\rightarrow D+E$

Total mass on reactant side = Total mass on product side

Hence, the correct answer is Option B.

. Given the reaction 2HgO → 2Hg + O2 , how many moles of elemental mercury will be obtained by the decomposition of 1 mole of Hg

AveGali [126]

Answer:

one mole of HgO will give one mole of Hg.

Explanation:

Given data:

Moles of HgO = 1 mol

Moles of Hg = ?

Solution:

Chemical equation:

2HgO → 2Hg + O₂

Now we will compare the moles of Hg with HgO from balance chemical equation.

HgO : Hg

2 : 2

1 : 2/2×1 = 1 mol

So, one mole of HgO will give one mole of Hg.

A chemist prepares a sample of helium gas at a certain pressure, temperature and volume and then removes all but a fourth of the

Stells [14]

Answer:

e. T₂= 4T₁

Explanation:

Initially, we have a number of moles (n₁) a gas sample at a certain pressure (P), temperature (T₁) and volume (V). We can relate these variables through the ideal gas equation.

P . V = n₁ . R . T₁

where,

R is the ideal gas constant

We can rearrange this equation like:

$T_{1}=\frac{P.V}{n_{1}.R}$

If only one fourth of the initial molecules remain n₂ = 1/4 n₁. The new temperature (T₂) assuming pressure and temperature remain constant is:

$P.V=n_{2}.R.T_{2}=\frac{1}{4} n_{1}.R.T_{2}\\\frac{P.V}{n_{1}.R} =\frac{1}{4} T_{2}\\T_{1}=\frac{1}{4} T_{2}\\T_{2}=4.T_{1}$

The carbon cycle is closely linked to which process?

ser-zykov [4K]

Answer:

Photosynthesis

Explanation:

Carbon cycle involves the exchange of components between the hydrosphere, biosphere and atmosphere. During carbon cycle, materials such as gases, minerals which are necessary for life are interchange. For example, animals pass out faeces on the soil which is rich in urea. Urea decomposes to provide nitrogen into the soil through bioactive bacterials. The nitrogen is used up by plants to grow. During photosynthesis, plants uses carbon dioxide and water to produce glucose and release oxygen for animals to use. It's like a purification system where one waste product from one organism is used by the other to survive.

Equation of photosynthesis

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂.
