the rock that the mountain is made from. how did these small pieces of rock break off from the mountain?
1. Wind and rain interacted with the rock breaking it into small pieces

2. The small pieces of rock were formed by earthquakes, tsunamis, and other natural disasters. These disasters were strong enough to break the rock into small pieces

3. Rays from the sun shone down on the rock, and it broke into pieces

4. if anything were left out for a long time, it would break into small pieces

An atom of sodium-23 (Na-23) has a net charge of +1. Identify the number of protons, neutrons, and electrons in the atom. Then,
kolezko [41]

Answer:

Number of proton is 11

Number of neutrons is 12

Number of electrons is 10

Explanation:

For a neutral Na, Sodium atom:

The mass number P+N = 23

Atomic number(E or P) = 11

A charged Na atom that has lost an electron is positively charged and so:

Number of proton = 11 (Still the same)

Number of neutrons = 12

Number of electrons = 11-1=10 (the atom has lost an electron)

If an atom loses electron, it becomes positively charged ie P>E

Um átomo X possui 8 neutrons e seu número atômico e igual a 8. Sabendo que esse atomo é isótopos de Y, que possui número de mass
hodyreva [135]
<u>Question in English : </u>
<span>
<em>An atom X has 8 neutrons and its atomic number equals 8. Knowing that this atom is isotopes of Y, which has mass number 18, answer: What is the number of neutrons in atom Y?</em>

</span><span><u>Answer :</u>

</span>

Isotopes are defined as the atoms which have same number of protons but different number of neutrons of same element. Since the proton number is same, the atomic number also same. Hence the atomic number of Y is 8.

Mass number = atomic number + neutron number

                   18 = 8 + neutron number

Neutron number = 10

 

Hence, there are 10 neutrons in Y.

You wash dishes for a chemistry laboratory to make extra money for laundry. You earn 12 dollars/hour, and each shift lasts 75 mi
nadezda [96]

Answer:

A)You must work 2 shifts to wash 10 loads of laundry

B)You can wash 15 loads pf laundry if you work for 3 shifts

C) each shift will pay for 3.75 loads of laundry if the cost per load rises to 16 quarters

Explanation:

Given:

amount  earned =   12 dollars/hour

Duration for one shift = 75 minutes

Amount needed for Laundry = 12 quarters/load.

A. How many shifts must you work if you wish to wash 10 loads of laundry

To wash 10 loads, you will be requiring

=> 10 \times 12 \text{quarters}

=> 120 quarters

1 quarter = 0.25 dollars---------------------------------(1)

120 quarters

= 120 \times 0.25 \text{ dollars}

= 30 dollars

You need 30 dollars for washing 10 loads

In one hour i,e 60 minutes you earn=  12 dollars

In one minute the amount earned will be

= \frac {12}{60}

= 0.2 dollar-------------------------------------------------------(2)

Now to earn 30 dollars you have to work for

=30 \times 0.2 minutes

= 150 minutes

Thus the number of shifts will be  

= \frac{150}{75}

= 2 shifts

B. How many loads of laundry can you wash if you work 3 shifts

We Know that 1 shift =  75 minutes

So 3 shifts = 75 \times 3 = 225 minutes

From (2),

In 1 minute = 0.2 dollars is earned

So in  225 minutes =  225 \ times 0.2 = 45 dollar is earned

45 dollar = 45 \times 4 = 180 quarters

You can wash 1 load with 12 quarters

With 180 quarters you can wash = \frac{180}{12} = 15 loads

C. How many loads of laundry will each shift pay for if the cost per load rises to 16 quarters

Cost per load = 16 quarters

From (1)

16 quarters = 0.25 \times 16  = 4 dollars per load

From (2) In 1 shift the amount earned will be

=> 75 \times 0.2

=15 dollars

With 4 dollars you can wash 1 load

So with 15 dollars = \frac{15}{4} = 3.75 loads
