Answer:nonmetals
Explanation:
Elements with high electronegativities have a stronger tendency to attract electrons than elements with lower electronegativities.
Answer: 1739.6g
Explanation:
P1 = 7.04MPa
T1 = 25°C = 25 + 273 = 298K
n1 = 150mol
P2 = 2MPa
T2 = 19°C = 19 + 273 = 292K
n2 =?
n1T1/P1 = n2T2/P2
(150x298)/7.04 = (n2x292)/2
7.04xn2x292 = 150x298x2
n2 = (150x298x2) /(7.04x292)
n2 = 43.49moles
Molar Mass of Ar = 40g/mol
Mass = n x molar Mass = 43.49x40 = 1739.6g
The new concentration of the solution that has 400.0 mL of a 0.425 M solution of NaCl diluted to 900.0 mL is 0.189M
HOW TO CALCULATE CONCENTRATION:
- The concentration of a diluted solution can be calculated using the following formula:
C1V1 = C2V2
Where;
- C1 = initial concentration
- C2 = final concentration
- V1 = initial volume
- V2 = final volume
- According to this question, a solution of NaCl has 400.0 mL of a 0.425 M solution and diluted to 900.0 mL. The new concentration is as follows:
400 × 0.425 = 900 × C2
170 = 900C2
C2 = 170 ÷ 900
C2 = 0.189M
- Therefore, the new concentration of the solution that has 400.0 mL of a 0.425 M solution of NaCl diluted to 900.0 mL is 0.189M.

Answer:
genes are small sections of DNA. These genes contain instructions that tell your cells to make molecules called proteins. And the protein do things to your body to keep you healthy. Genes determine traits as well.
It says cut it in half so the density would become 4g/mL and the Volume would become 5mL
