Answer:
I am looking for this as well. Can someone please help!
Explanation:
Answer:
True
Explanation:
A neutron, like the name implies, is neutral with no net charge. The charge is believed to be from the charge of the quarks that make up the nucleons (protons and neutrons).
Very glad I could help you!!
Answer:
the rate slow down
Explanation:
there is less kinetic energy in the system so fewer molecules will have the required energy to overcome the activation energy barrierv
A neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water. The neutralization of a strong acid and strong base has a pH equal to 7.
Answer:
59K
Explanation:
Using the general gas law equation:
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas constant (0.0821 Latm/molK)
T = temperature (K)
According to the information given in the question;
- mass of hydrogen gas = 20.2g
mole = mass/molar mass
mole = 20.2/2.015
mole = 10.01mol
- Pressure = 110 Kpa
1 kilopascal = 0.00987 atmosphere
110kPa = 110 × 0.00987
= 1.09atm
- Volume = 4.45 x 10^-2 kL
1 kL = 1000L
4.45 x 10^-2 kL = 4.45 x 10^-2 × 10³
4.45 × 10¹
= 44.5L
Using PV = nRT
T = PV/nR
T = 1.09 × 44.5/0.0821 × 10.01
T = 48.505/0.821
T = 59.02
T = 59K
