Answer:
The Answer is A
Explanation:
particles in gas much like any other particles vibrate. but gas is moving constantly so the answer would be A
The combination sounds like it'd be a powerful disinfectant, but the two should never be mixed. "Together, they produce chlorine gas, which even at low levels, can cause coughing, breathing problems, and burning, watery eyes," says Forte.
Answer:
D
Explanation:
The scientist identifies the need to make a drug to cure the respiratory illnesses.
n = number of mole of sample of helium gas = 7.16 x 10⁻⁴ moles
T = temperature of the gas = temperature of the bulb ?
V = Volume of helium gas = 75 mL = 7.5 x 10⁻⁵ m³
P = pressure of the helium gas = 116.8 kPa = 116.8 x 10³ Pa (1 k = 1000)
Using the equation
P V = n R T
inserting the values
(116.8 x 10³) (7.5 x 10⁻⁵) = (7.16 x 10⁻⁴) (8.314) T
T = 1471.6 C
Answer:
B
Step-by-step explanation:
Equation B is balanced. It has four atoms of H and four of O on each side of the reaction.
A is <em>wrong</em>. It has two atoms of Cl on the left and only one on the right.
C is <em>wrong</em>. It has two atoms of O on the left and four on the right.
D is <em>wrong</em>. It has two atoms of Cl on the left and only one on the right.
