Answer:
talc mineral and magnetite
Explanation:
KE = (1/2)(m)(v^2)
KE = (1/2)(7)(4^2)
KE = (1/2)(112)
KE = 56 J
Answer:
The total pressure will be 1, 021 atm
Explanation:
We apply Dalton's law, where for a gas mixture the total pressure is the sum of the partial pressures of each gas that makes up that mixture. The unit of pressure is converted into atm:
760mmHg----1 atm
542mmHg----x=(542mmHgx 1 atm)/760mmHg=0,713 atm
234mmHg----x=(234mmHgx 1 atm)/760mmHg=0,308 atm
Pt=P Ne + P At= 0,713 atm + 0,308 atm= <em>1, 021 atm</em>
Answer:
a mutation is a change in a DNA sequence
Explanation:
mutations can result from DNA copying mistakes made during cell division
Answer:
partial negative is O(oxygen) and partial positive is (H) Hydrogens
Explanation:
Because the molecule has covalent bonds, all charges are partial.
Partial negative is O(oxygen) and partial positive is (H) Hydrogens.
