Answer:
gravity?
Explanation:
since it's being taken down
Answer:
protons but different number of neutrons.
Explanation:
Answer:
0.0125mol
Explanation:
Molarity (M) = number of moles (n) ÷ volume (V)
n = Molarity × Volume
According to this question, a 0.05M solution contains 250 mL of NaOH. The volume in litres is as follows:
1000mL = 1L
250mL = 250/1000
= 0.250L
n = 0.05 × 0.250
n = 0.0125
The number of moles of NaOH is 0.0125mol.
Answer:
Partial pressure of Ar = 4.7 atm
Explanation:
Total pressure of a mixture of gases = Sum of partial pressure of each gas
This mixture contains: O₂, He and Ar.
Total pressure = 15.3 atm
Total pressure = Partial pressure O₂ + Partial pressure of He + Partial pressure of Ar
15.3 atm = 7.4 atm + 3.2 atm + Partial pressure of Ar
Partial pressure of Ar = 15.3 atm - 7.4 atm - 3.2 atm
Partial pressure of Ar = 4.7 atm
Answer:
<h3>When an electric current flows in a wire, it creates a magnetic field around the wire. This effect can be used to make an electromagnet . A simple electromagnet comprises a length of wire turned into a coil and connected to a battery or power supply.</h3>
