Answer:

the answer is:

no, because the reactivity of elements decreases from right to left on the periodic table.

Explanation:

In Metals:

Period - reactivity decreases as you go from left to right.

Group - reactivity increases as you go down a group

In Non-metals

Period - reactivity increases as you go from the left to the right.

Group - reactivity decreases as you go down the group.

Reactivity:

The reactivity of the elements increases going from left to right on the periodic table. Each element going from left to right tends to be more reactive. The electronegativity increases going from left to right, and it decreases going down the table.

hope this helps!!

Balance the equation for the reaction of benzene and hydrogen to form cyclohexane.. C6H6 + H2 → C6H12.

Vedmedyk [2.9K]

Here is a universal law to balance chemical equations :
All chemical equations must be balanced because of the law of conservation of mass.
It states that "matter cannot be created or destroyed."
So, the number of atoms that you start with at the beginning of the reaction must equal the number of atoms that you end up with.
keeping this law in our mind,lets balance the equation for the reaction of benzene and hydrogen to form cyclohexane.
C 6 H 6 + H 2 → C 6 H 12.
Here is the balance chemical equation.
2 C 6 H 6 + 6 H 2 → 2 C 6 H 12.

16.25 g of water at 54 C relaeases 402.7 J. What will be its final temp?

leonid [27]

Data:
Q = 402.7 J → releases → Q = - 402.7 J
m = 16.25 g
T initial = 54 ºC
adopting: c = 4.184J/g/°C
ΔT (T final - T initial) = ?

Solving:

Q = m*c*ΔT
-402.7 = 16.25*4.184*ΔT
-402.7 = 67.99*ΔT
$\Delta\:T = \frac{-402.7}{67.99}$
$\boxed{\Delta\:T \approx -5.92\:^0C}$

If: ΔT (T final - T initial) = ?
$-5.92^0 = T_{final} - 54^0$
$T_{final} = 54^0 - 5.92^0$
$\boxed{\boxed{T_{final} = 48.08\:^0C}}\end{array}}\qquad\quad\checkmark$

9.31g is the same mass as ?

Dmitry_Shevchenko [17]

Answer:

9.31 g = 0.00931 kg

Explanation:

We need to tell that 9.31 gram is same as what. There are many units that measure the meass of an object like milligram, kilogram, centigram etc.

The relation between kilogram and gram is as follows :

1 kg = 1000 g

1 g = 0.001 kg

If we change 9.31 gram to kg, we get :

9.31 g = (9.31 × 0.001) kg

$9.31\ g=9.31\times 10^{-3}\ kg\\\\=0.00931\ kg$

Hence, 9.31 g is the same mass as 0.00931 kg.

Which of the following mixtures could not be separated by filtration

____ [38]

The answer to this question would be Salty water(i think its the most likely to go through) because salt water is a homogeneous mixture so it would go through.
