One atom of silicon is perfectly combined with the \boxed{{\text{two atoms of oxygen}}}  and forms silicon dioxide.

Further explanation:

Law of multiple proportions:

This law states that the molecule is a particle that is made up of two or more element. The elements are always combined in a ratio of fixed whole number.

Silicon has electron configuration \left[{{\text{Ne}}}\right]3{s^2}3{p^2}  so it can form 4 covalent bonds with other atoms.

One atom of silicon is combined with hydrogen in 1:4 ratio and form {\text{Si}}{{\text{H}}_4} . This compound is known as silane. Thus silicon is not able to combine with three hydrogen atoms.

One atom of silicon is combined with calcium as calcium silicate \left({{\text{C}}{{\text{a}}_{\text{2}}}{\text{Si}}{{\text{O}}_{\text{4}}}}\right)   and Calcium silicon \left({{\text{Ca}}{{\text{H}}_{\text{4}}}{\text{Si}}}\right) . Therefore, silicon would not be able to combine with 4 calcium simultaneously.

One atom of silicon is combined with oxygen in 1:2 ratio and form {\text{Si}}{{\text{O}}_2} . This compound is known as silicon dioxide. Thus silicon can combine with two oxygen atoms.

One atom of silicon is combined with chlorine in 1:4 ratio and form {\text{SiC}}{{\text{l}}_4} . This compound is known as silicon tetrachloride. Thus silicon is not able to combine with one chlorine.

What type of bonding exists between the carbon atoms to create diamond ?
Step2247 [10]

Answer:

Covalent bonds.

Explanation:

Diamond is organized in a giant lattice structure with strong covalent bonds between carbon atoms. Each carbon atom forms 4 bonds. Explanation: Each carbon atom has four electrons in its outer shell, all of which form covalent bonds that are strong and hard to break.

216 J of energy is required to raise the temperature of a piece of aluminum from 15.0º C to to 35º C.
ddd [48]

Answer: 12g

Explanation:

The amount of energy (Q) required to raise the temperature of a substance depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)

Thus, Q = MCΦ

Given that:

Q = 216 joules

Mass of aluminium = ? (let unknown value be Z)

C = 0.90 JºC-1g-1

Φ = (Final temperature - Initial temperature)

= 35°C - 15°C = 20°C

Then, Q = MCΦ

216 J = Z x 0.90 JºC-1g-1 x 20°C

216 J = Z x 18 J°g-1

Z = (216J/18 J°g-1)

Z = 12g

Thus, the mass of the aluminium is 12grams

This stadium can hold 100,000, or 1 x 10^5, people. The number of atoms in a grain of iron is about 1 x 10^18. Would you need 1 
polet [3.4K]
<h3>Answer:</h3>

1 x 10^13 stadiums

<h3>Explanation:</h3>

From the question;

1 x 10^5 people can fill 1 stadium

We are given,  1 x 10^18 atoms of iron

We are required to determine the number of stadiums that  1 x 10^18 atoms of iron would occupy.

We are going to assume that a stadium would occupy a number of atoms equivalent to the number of people.

Therefore;

One stadium =  1 x 10^5 atoms

Then, to find the number of stadiums that will be occupied by  1 x 10^18 atoms;

No. of stadiums = Total number of atoms ÷ Atoms in a single stadium

                           =  1 x 10^18 atoms ÷  1 x 10^5 atoms

                          =  1 x 10^13 stadiums

Therefore,  1 x 10^18 atoms of iron would occupy  1 x 10^13 stadiums
