Answer:
$17
Explanation:
$4.75 is equal to 0.75 * x value, where x is the weekly allowance
$4.75=0.75x
$17=x
Answer:
AX₂
Explanation:
Binary compounds:
The compounds which are made up of the atoms of only two elements are called binary compounds.
For example:
The following compounds are binary:
HCl
H₂O
NH₃
HCl is binary because it is composed of only hydrogen and chlorine. Ammonia is also binary compound because it is made up of only two elements nitrogen and hydrogen.
water is also binary because it is also made up of only two elements hydrogen and oxygen.
In given question it is stated that the charge of cation is twice than the anion which means its charge would be +2 thus anionic part will have the charge -1. In neutral compound the positive and negative charges must be equal in magnitude to cancel the effect of each other and make the compound neutral. So, there must be two anionic atom present so that charge becomes -2 and cancel the +2 charge of cationic part. Thus the formula will be,
AX₂
A⁺²X₂⁻²
<span>Since the answer is in grams, kilograms must first be converted to grams. A kilogram is equivalent to 1000 grams. Therefore, multiply 1.2 kilograms by 1000 and you get 1,200 grams. Then, calculate the number of hours in 5 days. Each day is 24 hours and 24 hours multiplied by 5 days equals 120 hours. Lastly, since the answer is in grams per hour, divide 1,200 grams by 120 hours and the resultant rate of reaction is 10 g/hr.</span>
Different forms of matter have different melting/boiling points. For example, at 100 degrees Celsius, H2O (water) will turn from lliquid to gas. But NaOH (table salt) doesn't even go from solid to liquid until some 800 degrees Celsius. So, in order to figure out which state matter is at 35 Celsius, you'd have to be more specific about what kind of matter...
