Answer:

True

Explanation:

When an atom has lost an electron, the overall charge is going to be positive

( + ) because there is more protons than electrons rather than a normal atom where the protons equal the number of electrons which means the overall charge is 0 since the protons cancel out the electrons but in this atom the protons is greater than the electrons so the charge is positive

Answer:

True.

Explanation:

Electrons have 1 negative charge  so when a neutral atom loses 2 electrons it will have a charge of 2+.

The ph of a solution for which [OH]= 1.0 x 10^-4 is?<br><br> A 10<br> B 14<br> C 11<br> D 9<br> E 7
zhenek [66]
To find pH, use the following formula ---> pH= - log [H+]

so first we need to calculate the [H+] concentration using the OH concentration. to do this, we need to use this formula--> 1.0x10-14= [H+] X [OH-], so we solve for H+ and plug in

[H+]= 1.0X10-14/[OH-]---> 1.0 x 10-14/ 1.0 x 10-4= 1.0 x 10-10

now that we have the H+ concentration, we can solve of pH

pH= -log (1.0x10-10)= 10

answer is A

What can you conclude about these two reactions based on the chemical equations? Reaction A: 6CO2(g) + 6H2O(l) + sunlight ? C6H1
OlgaM077 [116]

Given reactions:

(A)   6CO2(g) + 6H2O(l) + sunlight → C6H12O6(aq) + 6O2(g)

(B)  2H2(g) + O2(g) → 2H2O(g) + energy

Exothermic reactions are those which proceed with the release of heat/energy. In contrast, endothermic reactions proceed with the absorption of energy in the form of heat or light.

Since reaction A required sunlight, it is endothermic. Reaction B releases energy, hence exothermic

Ans: (B)

A is endothermic

B is exothermic

What happens to glucose and oxygen that is produced by plants during photosynthesis ​
Virty [35]

Answer:

Respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce use able cellular energy. This energy is used to fuel growth and all of the normal cellular functions.

Short Answer

They combine to produce cellular energy.
