Answer:

b) Product

c) Combustion

c) speeds up the rate of reaction

Explanation:

the substance produced by a chemical reaction is called a product (b)

Combustion (c) reactions are involving oxygen and "another substance" [and hydrocarbons] to <em>produce carbon dioxide and water</em>.

A <em>catalyst </em>acts to speed up the rate of a reaction (c)

<em>  > note </em><em>how it "speeds up" reaction: , it [a catalyst] lowers the pressure or temperature needed to start one--but it isn't used/consumed in the reaction</em>

So, the answers are: b, c, c

hope this helps!!

Daniel [21]

Answer:

Check the explanation

Explanation:

Acidipic Acid <u><em>(which is an essential dicarboxylic acid for manufacturing purposes with about 2. 5 billion kilograms produced per year. It is mainly used for the production of nylon and its related materials.)</em></u>

Going by the question, since the H_{2}  CrO_{4} is comparatively mild oxidizing agent than the CrO_{3}, it only oxidizes the carbon group

Kindly check the attached image below for the full explanation to the question above.

How many grams of KBr is required to prepare 100 mL of<br> 2.0 M KBr solution?
sesenic [268]

Answer:

23.8g

Explanation :

Convert 2.0M into mol using mol= concentration x volume

2.0M x 0.1L (convert 100mL to L since the units for M is mol/L)

= 0.2 mol

We can now find grams by using the molar mass of KBr

=119.023 g/mol (Found online) webqc.org

but can be be calculated by using the molecular weight of K and Br found on the periodic table

We can now calculate the grams by using grams=mol x molar mass

119.023g/mol x 0.2mol

= 23.8046 g

=23.8g (rounded to 1decimal place)

A train travels at a speed of 30 miles per hour. If 1 mile = 1.6 kilometers, how fast is the train traveling in kilometers per m
Alina [70]
The answer 
 the speed of <span>the train traveling in kilometers per minute can be found by using the following method:
v = </span><span>30 miles per hour
</span><span>1 mile = 1.6 kilometers

just do the calculus by changing miles to kilometers
 </span>1 mile = 1.6 kilometers, so 30 miles= 1.6 km x 30 = 48 km
 so the speed of the train is
v=30 miles / hour = 48km / h = 48km / 60 mn  = 0.8 km/ mn
the answer is
<span>C- 0.8 km/min</span>
