Answer:
Given the balanced equation
CH4 (g) + 2O2 (g) → CO2 (g) + 2H2O (g)
we know that we'll get one mole CO2 for every 1 mole CH4. So let's calculate how many moles are in 50 g of CH4 by dividing it's mass by it's molar mass (16 g/mole). I get 3.125 moles. The equation says we should get the same number of moles of CO2, so set moles CO2 = 3.125 moles. Then we can find the mass of CO2 by multipying by the molar mass of CO2 (44 g/mole). We should expect 138 grams of CO2.

Answer:
453.6 g
Explanation:
The following data were obtained from the question:
Mole of Ag = 4.2 moles
Weight (in grams) of Ag =?
Thus, we can obtain the weight in grams of Ag by doing the following:
Mole of Ag = 4.2 moles
Molar mass of Ag = 108 g/mol
Mass of Ag =.?
Mole = mass /Molar mass
4.2 = mass of Ag /108
Cross multiply
Mass of Ag = 4.2 × 108
Mass of Ag = 453.6 g
Thus, the weight (in grams) of 4.2 moles of Ag is 453.6 g
Answer:
0.425 L
Explanation:
Given the information from the question. We know that the water heat evaporation is given by 2261 KJ/kg. Therefore, for each Kg of vapor, 2261 is required.
To calculate the amount of water evaporated by 960 KJ is as follows
= (1/2260)*960 =0.425 Kg
In other words, 0.425 of water is evaporated by 960 KJ.
To calculate the volume of water, we have mass and density. Therefore, Volume = Mass/Density = 425g/1g/ml = 0.425 L.
Therefore, water evaporated is 0.425 L

Answer:
Sodium hypochlorite (bleach) has the formula NaClO which means that it contains the three elements sodium (Na), chlorine (Cl) and oxygen (O). There are two atoms of oxygen in 2H2O.
