In what way do the atoms in the same row of the Periodic Table increase from left to right?

Chemistry

zheka24 [161]3 years ago
5 0

Answer:

As you move from left to right, the nucleus gains protons. This increases the positive charge of the nucleus and its attractive force on the electrons. At the same time, electrons are added to the atoms as you move from left to right across a period.

Interpret the equations in terms of particles moles and mass
pickupchik [31]

The equations in terms of particles moles and mass

a. 2PbS +3O2 = 2PbO +2SO2

b. 4HCl +O2 = 2H2O + 2Cl2

a) 2 Molecules of Pbs + 3 molecules of O2 = 2 Molecules of PbO + 2 molecules of SO2

2 Moles of PbS + 3 Moles of O2 = 2 moles of PbO + 2 Moles of SO2

478.6 grams of PbS+ 48 grams of 02 = 446.4 grams +  128 grams SO2

b). 4 molecules of HCl + 1 molecule of oxygen = 2 molecules of water +2 molecules pf Cl2

4 mole of HCl + 1 mole of oxygen = 2 mole of water + 2 moles of Cl2

146.4 grams of HCl + 31.8 grams = 36 grams of H20 + 159.8 grams of Cl2.

Explanation:

Calculation of:

particles =?

moles =?

mass =?

Equation given:

a) 2PbS +3O2 = 2PbO +2SO2

2 Molecules of Pbs + 3 molecules of O2 = 2 Molecules of PbO + 2 molecules of SO2

2 Moles of PbS + 3 Moles of O2 = 2 moles of PbO + 2 Moles of SO2

Mass of the reactant and product is calculated as:

number of moles x atomic mass

so,

atomic mass of PbS =239.3 grams/mole

mass = 2 x 239.3

          = 478.6 grams

atomic mass of O2 = 16 grams/mole

mass = 3 x 16

         = 48 grams

atomic mass of PbO = 223.2 grams/mole

mass = 2 x 223.2

         = 446.4 grams

atomic mass of SO2 = 64 grams/mole

mass = 2 x 64

          = 128 grams

b)  Calculation of:

particles =?

moles =?

mass =?

Equation given:

4HCl +O2 = 2H2O + 2Cl2

4 molecules of HCl + 1 molecule of oxygen = 2 molecules of water +2 molecules pf Cl2

4 mole of HCl + 1 mole of oxygen = 2 mole of water + 2 moles of Cl2

To calculate mass, formula used is

mass = number of moles x atomic mass

atomic mass of HCl =36.46 gram/mole

mass = 4 x 36.46 = 146.4 grams

atomic mass of oxygen

mass = 2x 15.9 = 31.8 grams

atomic mass of water = 18 grams,mole

mass = 2 x 18 = 36 grams

atomic mass of Cl2 = 79.90 grams/mole

mass = 2 x 79.90 = 159.8 grams

This balanced chemical equation represents a chemical reaction: 6no + 4nh3 → 5n2 + 6h2o what volume of nh3 gas, at standard temp
Liula [17]

The answer is: volume of ammonia gas is 7.4 L.

Chemical reaction: 6NO + 4NH₃ → 5N₂ + 6H₂O.

m(NO) = 15 g; mass of nitrogen(II) oxide.

M(NO) = 30 g/mol; molar mass of nitrogen(II) oxide.

V(NH₃) = ?

n(NO) = 15 g ÷ 30 g/mol.

n(NO) = 0.5 mol; amount of nitrogen(II) oxide.

From chemical reaction: n(NO) : n(NH₃) = 6 : 4.

0.5 mol : n(NH₃) = 6 : 4.

n(NH₃) = 0.33 mol; amount of ammonia.

Vm = 22.4 L/mol; molar volume at STP.

V(NH₃) = 0.33 mol · 22.4 L/mol..

V(NH₃) = 7.4 L.

A sample of carbon dioxide gas that has a volume of 14.6 L at STP contains how many
Nana76 [90]

Answer:

n = 0.651 mol

Explanation:

Given data:

Volume of CO₂ = 14.6 L

Temperature = standard = 273.15 K

Pressure = standard = 1 atm

Number of moles of CO₂ = ?

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

by putting values,

1 atm × 14.6 L = n × 0.0821 atm.L/ mol.K   × 273.15 K

14.6 L. atm =  n × 22.43atm.L/ mol

n = 0.651 mol

Chemistry question! Please explain!
Ilya [14]
There are no numbers provided so I will try to explain the equation. If you want to find the percent error you would do theoretical (the number it’s supposed to be) minus experimental (the number you got in the experiment) over the theoretical value (same as the first one.) You must multiply this by 100 in order to show the actual percentage rather than very low decimals. You want the percent error to be as low as possible because the lower it is the less mistakes happened. Mistakes can include too much/less of solvent, solution, or the glassware wasn’t clean enough, and much much more.

I hope this helps!
