Answer:

The missing reagents are.

Potassium + Iodine =<u> Potassium iodide</u>

<u>Calcium</u> + oxygen = Calcium oxide

Beryllium +<u> Bromine</u> = Beryllium bromide

<u>Copper + Oxygen</u> = Copper oxide

Explanation:

The balanced equation can be written as:

1.Potassium + Iodine =<u> Potassium iodide</u>

2K(s)+I_{2}(s)\rightarrow 2KI(s)

Here K = potassium

I2 = Iodine

KI = potasssium iodide.

2.<u>Calcium</u> + oxygen = Calcium oxide

2Ca(s)+O_{2}(g)\rightarrow 2CaO(s)

Ca = calcium

O2 = oxygen

CaO = Calcium Oxide

3.Beryllium +<u> Bromine</u> = Beryllium bromide

Be(s)+Br_{2}(g)\rightarrow BeBr_{2}(s)

Here,

Be = beryllium

Br2 = bromine

BeBr2 = Beryllium Bromide

4. Copper + Oxygen = Copper oxide

2Cu(s)+O_{2}(g)\rightarrow 2CuO(s)

Cu = Copper

O2 = oxygen

CuO = Copper Oxide

Choose whether the statements about oil sands are true or false. The viscosity of bitumen is about 100 times greater than the vi
Alexxx [7]

The First 2 statements stated above were false whereas the third one is a true statement.

Explanation:

  • The viscosity of bitumen is about 100 times greater than the viscosity of water - False

Reason - The viscosity of bitumen is about not 100 times greater than the viscosity of water, it is actually 100, 000 times greater.

  • Oil from oil sand deposits is only obtained by first heating the sands at high temperatures is False.

Reason- Oil from oil sand deposits is not obtained by first heating the sands at high temperatures but by using steams

  • Oil sands contain sand, water, and light crude oil is true.

A football was thrown 25m for a touchdown in 2.5s, How fast was the ball traveling?
Verizon [17]

Answer:

V=?

S=25m

t=2.5s

V=S/t

V=25/2.5

V=10m/s

So, the ball was traveling with the speed of 10m/s.

Describe two ways he could change the metal physically and two ways he could change the metal chemically to try to identify it.
slega [8]
Physical change is a change that occurs in a substance that does not change the identity of the substance. It does not alter the chemical structure of the molecules ehile chemical change involves the breaking of the bonds in the substance forming new substance. To identify a metal physically, we can use properties like their boiling and melting points. We can determine at what temperatures these metals melt or boil then from literature we compare the values. Another properties that can be looked upon to are hardness, color and density. For chemical methods, we can allow it to react with substances, that will produce precipitates containing the metal in question. Also, we can use other methods like titration method. All chemical methods involves the use of chemical reactions.
