What does the sun do to generate energy?
Kruka [31]
Within the core of the Sun, temperatures and pressures are high enough to fuse hydrogen atoms into helium, which is the Sun's main form of energy production. Assuming there was a slight mistake in where you have copied the results here the correct answer is the third option.
Hope this helps!

Calculate the number of ATOMS in 1.0 mole of O2.
Wewaii [24]
There is 6.02*10^23 molecule per mole. And there is 2 atoms per oxygen molecule. So the answer is 1.204*10^24 atoms in 1.0 mole of O2.

A student determines that a 9.8 g mixture of MgCl₂ (s) and NaNO3(s) contains 0.050 mol of
Damm [24]

mass MgCl₂ = mol x MM MgCl₂ = 0.05 x 95.211 g/mol = 4.76 g

mass Cl in MgCl₂ :

= (2 x AM Cl)/MM MgCl₂ x mass MgCl₂

= (2 x 35.5 g/mol)/95.211 g/mol x 4.76

= 3.55 g

% mass Cl in the mixture :

= (mass Cl / mass mixture) x 100%

=  3.55 / 9.8 x 100%

= 36.22%

g In the absence of allosteric effectors, the enzyme phosphofructokinase displays Michaelis–Menten kinetics (see Fig. 7.15). The
Furkat [3]

Answer:

The value of the Michaelis–Menten constant is 0.0111 mM.

Explanation:

Michaelis–Menten 's equation:

v_o=V_{max}\times \frac{[S]}{(K_m+[S])}=k_{cat}[E_o]\times \frac{[S]}{(K_m+[S])}

V_{max}=k_{cat}[E_o]

Where:

v_o = rate of formation of products

[S] = Concatenation of substrate

[K_m] =  Michaelis constant

V_{max}  = Maximum rate achieved

k_{cat} = Catalytic rate of the system

[E_o] = Initial concentration of enzyme

On substituting all the given values

We have :

\frac{v_o}{V_{max}}=0.90

[S] = 0.10 mM

\frac{v_o}{V_{max}}=\frac{[S]}{(K_m+[S])}

0.90=\frac{0.10 mM}{K_m+0.10 M}

K_m=0.0111 mM

The value of the Michaelis–Menten constant is 0.0111 mM.
