Lead II chloride + sodium nitrite is what?​

Chemistry
1 answer:
bixtya [17]3 years ago
8 0

Answer:

Sodium Chloride + Lead (II) Nitrite

Explanation:

- It's a double replacement reaction, meaning you you have to switch the first two or last two to form new compunds.

- If you want to balance it, it will be:

    Lead II Chloride + 2(Sodium Nitrite) -> 2(Sodium Chloride) + Lead II Nitrite

Don't write it like this. You should be writing the chemical formulas for each compund

What is the maximum mass of s8 that can be produced by combining 89.0 g of each reactant?
lidiya [134]

Answer : We can produce 125.7 g of S_{8}.


Explanation : The reaction will be

8SO_{2} + 16H_{2}S -----> 3S_{8} + 16H_{2}O


The molecular mass of SO_{2} is 64.1 g/mol

and molecular mass of H_{2}S is 34.1 g/mol


For every mole of SO_{2} we would need twice of H_{2}S moles, so for every 3 moles of S_{8} we need 16 moles of H_{2}S


Now, we can calculate number of moles S_{8}

2.61 X (3/16) = 0.49 moles


Here, the molecular mass of S_{8} is 256.8 g


multiplying it with the number of 0.49 moles we get, 256.8 X 0.49 = 125.7 g of S_{8}.


Hence, 125.7 g of S_{8} will be produced.

If I have 4 moles of a gas at a pressure of 5.6 atm and a volume of 12 Liters, what is the temperature in Kelvin(K)
kvv77 [185]

Answer:

205 K (to 3 significant figures)

Explanation:

Assuming that 4 moles of the gas behaves like an ideal gas and obey the kinetic molecular theory.

Let's apply the ideal gas law, pV= nRT.

Here p denotes the pressure of the gas, V is for volume, n is the number of moles of the gas, R is the universal gas constant and T is the temperature.

Substitute the given information into the equation:

5.6 atm ×12 L= 4 mol ×R ×T

Since pressure is in atm and volume is in L, we can use R= 0.08206 L atm K⁻¹ mol⁻¹.

5.6 atm ×12 L= 4 mol ×0.08206 L atm K⁻¹ mol⁻¹ ×T

T= 67.2 ÷0.32824

T= 204.73 (5 s.f.)

T= 205 K (3 s.f.)

The formation of a white cloud
saw5 [17]
Most clouds are white. That's because water and ice particles that make up a cloud have just the right amount and sizes to scatter light in all possible wavelengths. When light of practically all wavelengths combine, the result is white light.
