Since light rays travels in a straight line, the light traveling through the dark room can be seen before it hits the paper.

What are light rays?

Light rays refers to a straight line path through which light waves travel.

Light rays travel in a straight line and this phenomenon is known as the rectilinear propagation of light.

In a dark room, the path of light rays travelling in a straight can be seen.

Therefore, the light rays traveling through the room can be seen before it hits the paper.

In order to form water, two hydrogen atoms and one oxygen atom must be

A. dissolved.
B. bonded.
C. divided.
D. mixed.

Answers

Answer:

B bonded

Explanation:

Two molecules of hydrogen gas (two hydrogens bonded together) are combined with one molecule of oxygen gas (two oxygen atoms bonded together) in order to form two molecules of water (two hydrogen atoms bonded to one oxygen atom). What are covalent bonds? Covalent bonds occur when two or more atoms share electrons.

In order to form water, two hydrogen atoms and one oxygen atom must be bonded. The correct option is B.

What are covalent bonds?

Covalent bonds between two or more atoms occur when they share electrons. with each other.

Two molecules of hydrogen gas are combined with one molecule of oxygen gas which forms two molecules of water. Hydrogen take one electron and oxygen can donate two electrons. One oxygen shares two electron with two hydrogen with one electron gaining capacity.

Thus, in order to form water, two hydrogen atoms and one oxygen atom must be bonded. The correct option is B.

Answers

Answer:

I have seen many lightning storms before. However, one of the most surprising ones was when I was at my house. It was around midnight when I awoke from the sound of lightning in the distance. I was also half awake so this could be another reason this was the most surprising, but lightning struck near my area. i could see the light through my curtains and the sound was loud enough to awake everyone in my house, even the deep sleepers. I practically jumped out of bed.

1.0 mole of KCl(aq) is added to which solution to produce a precipitate?
A)
Lit
B)
Ca2+
Agt
D)
Zn2+

Answers

Answer:

Ag+

Explanation:

If you imagine as if the problem were double replacement, you would pair the Cl with one of the following ions provided in the choices. As seen on Table F, Ag+ paired with Cl- produces an insoluble compound, hence the precipitate. All the other ions shown in the multiple choice section, when paired with Cl- will produce a soluble compound, as a result NOT a precipitate.

If 0.25 moles of KBr is dissolved in 0.5 liters of
heavy water which has a mass of 1,100 grams
per liter, what is the concentration?
Answer in units of m (molal).

Answers

Answer:

[KBr] = 454.5 m

Explanation:

m is a sort of concentration that indicates the moles of solute which are contianed in 1kg of solvent.

In this case, the moles of solute are 0.25 moles.

Let's determine the mass of solvent in kg.

Density of heavy water, solvent, is 1.1 g/L and our volume is 0.5L.

1.1 g = mass of solvent / 0.5L, according to density.

mass of solvent = 0.5L . 1.1g/L = 0.55 g

We convert the mass to kg → 0.55 g . 1kg /1000g = 5.5×10⁻⁴ kg

m = mol/kg → 0.25 mol /5.5×10⁻⁴ kg = 454.5 m

In the reaction shown, how many moles of HCl are needed to react with 2.4 moles of Al?

7.2
Ob
6.4
Ос
0.8
d
1.3
е
4.8

Answers

Answer:

7.2 moles

Explanation:

Since the equation is balanced, we can use a mole ratio. 6 moles of HCl : 2 moles of Al. Thus, to convert, we simply multiply by 3.

Answer:

7.2 moles of HCl

Explanation:

The balanced reaction equation of the reaction is;

2 Al + 6 HCI ---------> 2 AlCl3 + 3 H2

We can see from the reaction equation that;

6 moles of HCl reacts with 2 moles of Al

Hence;

x moles of HCl reacts with 2.4 moles of Al

x = 6 * 2.4/2

x = 7.2 moles of HCl

What is the molecular formula for a compound that is 34.31% sodium, 17.93% carbon, 47.76% oxygen and has a molar mass of 134.00g?

Answers

Answer: Na2C2O4 probably sodium oxalate

Explanation: assume you have 100 g substance.

Mass of Na is m(Na) = 34.31 g, m(C) = 17.93 g and m(O) = 47.76 g.

Calculate moles n(Na) = 34.31 g/22.99 g/mol= 1.49 mol.

For C n(C) = 1.49 mol and n(O) = 2.985. You divide all by 1.49 you

Get n(Na) : n(C) : n(O) = 1:1:2 M(NaCO2) = 67 g/mol.

Divide 134:67 = 2. You get formula Na2C2O4
