How many moles of SnF2 will be produced along with 48 grams of H2

Chemistry
1 answer:
wolverine [178]3 years ago
5 0

Answer:

24 moles

Explanation:

given data

H_2 = 48 grams

to find out

how many moles of SnF_2 will be produced

solution

we know that Stoichiometry is here as

Sn+2HF\rightarrow SnF_2+H_2      ......................1

so we get here mole of solute H_2 that is express as

mole = \frac{\text{given mass}}{\text{Molar Mass}}      ..........................2

put here value for H_2  

mole = \frac{48}{2}  

mole of H_2 = 24 mole

and

we can say that here as per equation 1 that one mole of H_2  is go with one mole of SnF_2

so here H_2 24 mole is go with 24 moles mole of SnF_2  

so we can say SnF_2 will be produced 24 moles

A sample of air has a volume of 140.0 mL at 67C. To w
bonufazy [111]

Answer:

What that means is that when pressure and number of moles are kept constant, increasing the temperature will result in an increase in volume. Likewise, a decrease in temperature will result in a decrease in volume. In your case, the volume of the gas decreased by a factor of about 3, from "140.0 mL" to "50.0 mL".

What is the volume of 0.80 grams of O2 gas at STP? (5 points) Group of answer choices 0.59 liters 0.56 liters 0.50 liters 0.47 l
Anarel [89]

Answer:

0.56 liters

Explanation:

First we <u>convert 0.80 grams of O₂ into moles</u>, using its molar mass:

  • 0.80 g ÷ 32 g/mol = 0.025 mol

At STP, 1 mol of any given mass occupies 22.4 L. With that information in mind we <u>calculate the volume that 0.025 moles of O₂ gas would occupy</u>:

  • 0.025 mol * 22.4 L/mol = 0.56 L

Thus the answer is 0.56 liters.

How many grams of H2O are needed to produce 150 g of Mg(OH)2? (Molar mass: H2O = 18.02 g/mol; Mg(OH)2 = 58.33 g/mol )
Nuetrik [128]

Answer:

92.6

Explanation:

6 mol x 18.02 g of H2o --> 3 mol x 58.33 g  Mg(OH)2

108.12 g of h2o --> 174.99 of Mg(OH)2

g of H2O is 150 g of Mg(OH)2

150g x 108.12g / 174.99 =

92.67

The options are: ( it can’t be repeated )
Artyom0805 [142]

Answer:

3- gamma radiation

Explanation:

Hello,

In the above question, 4 of the options are related to polymerization which are

1. Synthetic polymer

2. Natural polymer

3. Condensation polymerization

4. Addition polymerization.

The first two options are types of polymer that exists while the last two are polymerization techniques.

The odd option here which is "gamma radiation" is a particle which is emitted from radioactive substances during decay. It has no mass and no charge but it is highly penetrating and dangerous to human health.

However,

Synthetic polymers are also known as man made polymers and they exist around us because they're present in materials which we use everyday. An example is polyethylene, nylon-6,6 etc

Natural polymers are compounds which are polymeric in nature (compounds catenating to form a complex molecule). Natrual occurring polymers can be found in proteins and some lipids.
