Both of them don’t follow the law of conservation of mass

12.) This does not follow the rule of conservation because on the reactant side there is one Na and two Cl while the product side only has one Na and Cl. They are not equal and do not have the same number of atoms for the different elements. In the law of conservation matter cannot be created or destroyed and this does not follow the law.

13.) 2Na + Cl2 —> 2NaCl

Put a 2 in front of Na and a 2 in front of NaCl

barxatty [35]

Answer:

<u><em>Ms. Felix would spend $491.75 on her order.</em></u>

Step-by-step explanation:

First, let's identify the components of this word problem that we'll need to solve it. We know that Staples charges $28 for 8 boxes of pencils, and $47 for 4 pencil sharpeners. Before we do anything else, we'll find the unit price of  the pencils and pencil sharpeners to make it easier for us. Let's begin with the boxes of pencils. 28 ÷ 8 = $3.50 per box of pencils. As for the pencil sharpeners, 47 ÷ 4 = $11.75 per sharpener. Now that we know the basic costs, let's use them to solve our problem at hand. We'll multiply the number of items ordered by the base cost of the item.

Boxes Of Pencils:

70 × $3.50= $245.00

Sharpeners:

21 × $11.75= $246.75

Now that we know the cost of the two seperate items Ms. Felix ordered, let's add them to get our final answer.

<h3>$245 + $246.75 = $491.75</h3><h3 />

Our final answer would be $491.75.

The marked prize of a bicycle is Rs 5550. What will the prize of a bicycle if the 15% VAT was leived allowing 10% discont on it?
Charra [1.4K]

Answer:

Rs 5,744.25

Step-by-step explanation:

The computation of the prize of a bicycle in the case when there is a 10% discount and 15% VAT is applied is shown below:

= Market price - discount + Vat applied

= Rs 5,550 - Rs 5,550 × 10% + 15% of the amount

= Rs 5,550 - Rs 555 + 15% of the amount

= Rs 4,995 +  Rs 4,995 × 15%

= Rs 4,995 + 749.25

= Rs 5,744.25
