laiz [17]1 year ago
5 0

Explanation:

The emission of a beta particle is the result of the rearrangement of the unstable nucleus of the radioactive atom in order to acquire stability. For that, a phenomenon occurs in the nucleus, in which a neutron decomposes giving rise to three new particles: a proton, an electron (β particle), and a neutrino. The antineutrino and electron are emitted. The proton, however, remains in the nucleus.

The symbol is used to represent beta particles.

Answer: b. Beta

Calculate the volume of dry co2 produced at body temperature (37 ∘c) and 0.970 atm when 25.5 g of glucose is consumed in this re
katrin2010 [14]

I believe the balanced chemical equation is:

C6H12O6 (aq) + 6O2(g) ------> 6CO2(g) + 6H2O(l) 

 

First calculate the moles of CO2 produced:

moles CO2 = 25.5 g C6H12O6 * (1 mol C6H12O6 / 180.15 g) * (6 mol CO2 / 1 mol C6H12O6)

moles CO2 = 0.8493 mol

 

Using PV = nRT from the ideal gas law:

<span>V = nRT  / P</span>

V = 0.8493 mol * 0.08205746 L atm / mol K * (37 + 273.15 K) / 0.970 atm

<span>V = 22.28 L</span>

If one atom of potassium and one atom of chlorine form an ionic bond, what are the charges of the two ions?
fiasKO [112]

Answer:

The answer is the letter A.

Explanation:

It is letter A because of Chlorine needs an electron to have a full shell. So, it will receive a negative one because it is gaining an electron. Potassium lost an electron because the element has to share the electron with Chlorine to balance its properties.

What volume of a 9.00 M NaOH stock solution would you need to make 800. ML of a 0.750 M NaOH solution
joja [24]

Answer: 66.66 ml

Explanation: Using Molarity equation:

M_1V_1 (stock solution)=M_2V_2(solution to be prepared)

given: M_2=0.750M

V_2=800ml

M_1=9.00M

V_1=?

9.00M\times V_1 (stock solution)=0.750M\times 800ml (solution)

V_1= 66.66ml
