I believe the correct answer would be decreases. At constant temperature, the volume and pressure are inversely related that is when one value increases the other decreases or as one decreases the other increases. Hope this helps. Have a nice day.
Answer:
Explanation:Due to the mental pressure,
Due to peer pressure,
Lack of love and affection from the family members.
Influence from the T.V advertisement.
Decrease in temperature is -126.0°C
<u>Explanation:</u>
Using Charles law we can set up the equation as,
V₁/T₁ = V₂/T₂
(2.00 L) / 294.0 K) = (1.00 L) / (x)
cross multiply to get:
2x = 294
2x/2 = 294/2
x = 147.0 K
Now kelvin is converted into Celsius by subtracting 273 from 147 as,
147 - 273 = -126°C
You need the molercular mass of Sucrose.
You can either search the molecular formula of Sucrose and calculate the molecular mass, or search directly the molecular mass.
Here you have both:
Molecular mass of sucrose: 342.30 g / mol
Chemical formula of sucrose: C12 H22 O11 (if you want to just must multiply the number of each atom by its atomic mass to get the molecular mass).
Calculate the number of grams of O in that molecule:
O: 11 * 16.00 g/mol = 176.0 g of O.
Now use proportions:
176 g O / 342.30 g sucrose = x / 50.00 g sucrose
=> x = 50.00 g sucrose * 176.0 g O / 342.30 g sucrose =25.71 g O.
Answer: 25.17 g
Answer:
Atom then element
Explanation:
Scientists once thought the most fundamental building block of matter was a particle called the atom. Now we know that the atom is made of many smaller pieces, known as subatomic particles. Every atom contains a central core called the nucleus, made of particles called protons and neutrons.
An element is a pure substance and is made of only one type of atom; it cannot be broken down into a simpler substance.
