Ten name if this compound is Potassium Oxide
Answer:
C. an archaea cell
Explanation:
Both bacteria and archaea have a cell wall, but the bacteria cell wall has peptidoglycan. The archaeal doesn't have peptidoglycan, but some unique proteins. They both also don't have nuclei. A virus doesn't have a cell wall, and a host cell, if eukaryote, would have a nucleus.
Answer: C - The iron becomes harder and stronger
Explanation:
The pure iron when mixed with the carbon then steel is formed which is the interstitial alloy of iron. About 0.002%- 2.1% (m/m) of carbon. The carbon atoms being smaller than the iron atom occupy the interstitial spaces or interstices in between the iron atoms. Thus these carbon atoms introduce imperfections in the iron crystal layer. The iron crystal layers become harder and they slide past one another and the iron becomes harder.
Answer:
C3H6 + 9/2 O2 ⇒ 3CO2 + 3 H2
according to the equation, mole of O2 =9/2 * mole of C3H6
so the liters of O2 gas = 9/2 * C3H6 gas = 9/2 * 0.61 =2.745l
similarly, according to the equation, CO2 gas = 3 * C3H6 gas=3*0.61=1.83l
Explanation:
Answer:
Na+Cl- + Ag+no3- ---> Na+No3- + Ag+Cl-
A spectator ion is an ion that exists as a reactant and a product in a chemical equation
Explanation:
When a solution of sodium hydroxide, NaOH, is mixed with hydrochloric acid, HCl, the compounds dissociate into the ions Na+, OH-, H+ and Cl-. The hydrogen and hydroxide ions react to form water, but the sodium and chlorine ions stay in solution unchanged.
