The pressure on 30 milliliters of an ideal gas increases from
760 torr to 1520 torr at constant temperature. The new volume is
Answers
V1 = 30 mL
P1 = 760 torr
P2 = 1520 torr
V2 = ?
applying Boyle's Law
P1*V1 = P2*V2
760 torr * 30 mL = 1520 torr * V2
V2 = 760 torr * 30 mL / 1520 torr
( C ) is correct

How many moles of a gas are in a 2.2-liter balloon at 600 mmHg and 85 C. Also asks to identify the P, V, N, R, and T. If unknown then put "?"
Answers
V = 2.2 L
T = 85°C
R = 0.08206 L atm / mol K
n = ?
I would start by converting the P from mmHg to atm, since our gas constant R uses atm.
600 mmHg • 1 atm / 760 mmHg = 0.789 atm = P
Then I would convert T from Celsius to Kelvin, since our gas constant R uses Kelvin.
85 + 273 = 358 K
Now you can solve PV = nRT for n, giving you:
n = PV/RT
n = (0.789 atm)(2.2 L) / (0.08206 L atm / mol K)(358 K) = 0.059 moles of gas
We have that for the Question "How many moles of a gas are in a 2.2-liter balloon at 600 mmHg and 85 C." it can be said that Moles of gas is
n= 0.059 moles of gas
From the question we are told
How many moles of a gas are in a 2.2-liter balloon at 600 mmHg and 85 C. Also asks to identify the P, V, N, R, and T. If unknown then put "?"
Generally the equation for the is mathematically given as
[tex]P=\frac{600}{760}\\\\P=0.789atm[/tex]
Therefore
[tex]n=\frac{PV}{RT}\\\\Therefore\\\\n=\frac{PV}{RT}\\\\n=\frac{0.789*2.2}{0.08206*(85 + 273)}\\\\[/tex]
n= 0.059 moles of gas
Therefore
Moles of gas is
n= 0.059 moles of gas

For the reaction
C2H2(g) + 3 O2(g) – 2 CO2(g) + 2 H2O(g)
What number of grams of CO2 could be produced from 2.0 g of C2H4 and 5.0 g of O2?
Answers
Answer:
3.3792 g
Explanation:
The balanced equation for the reaction is given as;
2 C2H2(g) + 3 O2(g) --> 2 CO2(g) + 2 H2O(g)
From the reaction;
2 mol of C2H2 requires 3 mol of O2
2.0 g of C2H2
Number of moles = Mass / Molar mass = 2 / 26.04 = 0.07680 mol
5.0 g of O2
Number of moles = Mass / Molar mass = 5 / 32 = 0.15625 mol
The limiting reactant is; C2H2
2 mol of C2H2 produces 2 mol of CO2
0.07680 mol produces x
Solving for x;
x = 0.07680 mol
Mass = Molar mass * Number of moles = 44 g/mol * 0.07680 mol = 3.3792 g
Which of the following describes an exothermic reaction?
Answers
An exothermic reaction is described by ΔH(reactants) is greater than ΔH( products) and the correct option is option A.
What is Exothermic reaction?The word exothermic means “releasing heat.” Energy, often in the form of heat, is released as an exothermic reaction proceeds.
Enthalpy of a reaction is defined as the heat energy change (Δ H) that takes place when reactants go to products. If heat is absorbed during the reaction, Δ H is positive; if heat is released, then Δ H is negative.
ΔH value negative –> energy released –> exothermic reaction
ΔH value positive –> energy absorbed –> endothermic reaction
Therefore, an exothermic reaction is described by ΔH(reactants) is greater than ΔH( products) and the correct option is option A.

Answers
Answer:
Covalent bonding is a type of chemical bonding which is characterized by atoms sharing electrons. For nitrogen and chlorine to covalently bond, nitrogen needs 3 electrons. Chlorine only has one electron therefore two more chlorine molecules are needed. Because one atom of nitrogen needs 3 atoms of chlorine to bond, the formula will be NCl3.

Beryllium has 2 electrons in their outermost shell and has highly reactive than boron because Boron needs 3 electrons to lose whereas, beryllium needs to lose only 2 electrons to get stability. Silicon has 4 electrons in its outermost shell and is less reactive than aluminum because aluminum has to lose 3 electrons to get stability as compared to silicon which needs 4 electrons to lose to be stable and non-reactive.
