Answer:
B. At room temperature, fats are solid and oils are liquid.
Explanation:
Fats and oils are one of the the three macronutrients (the other two are protein and carbohydrates).
However, fats and oils are different from each other: fats are mainly obtained from animals, while oils are mainly obtained from vegetable sources.
The major difference between fats and oil is that fats are composed of high amounts of saturated fatty acids which makes them solid at room temperature, while oils are composed of mainly unsaturated fatty acids which makes them liquid at room temperature.
Note that: in daily use the two terms may be used interchangeably.
It is B. When at room temperature fats are solid and oils are liquids.
Answer:
V = 134.5 L
Explanation:
Given data:
Number of moles of KClO₃ = 4 mol
Litters of oxygen produced at STP = ?
Solution:
Chemical equation:
2KClO₃ → 2KCl + 3O₂
Now we will compare the moles of KClO₃ with oxygen.
KClO₃ : O₂
2 : 3
4 ; 3/2×4 = 6 mol
Litters of oxygen at STP:
PV = nRT
V = nRT/P
V = 6 mol × 0.0821 atm.L/mol.K × 273 K / 1atm
V = 134.5 L / 1
V = 134.5 L
Since the hydrangeas are changing color depending on whether the soil is acidic or basic, they must have an indicator. This means that any hydrangea planted in acidic soil will have blue flowers and any hydrangea planted in basic soil will have pink. One common indicator present in many plants is anthocyanin, so maybe hydrangeas contain that chemical.
I think the soil has a lot to do with the reason why the flowers have different colors.
A soil is a mixture of organic matter that supports life. There are 4 types of soil which are sand, silt., clay and loam soil.
A hydrangea flower is affected by the acidity of the soil to influence the color it turns out to be.
The acidic property in the soil used to plant the flower turned it blue,
while The alkaline property in the soil turned the color pink.

B) one Neutron
C) six Electrons
D) These masses are too tiny to measure
Answer:
C
Explanation:
Answer:
six electrons
Explanation:
Electrons have almost virtually no mass and much less than a proton and neutron.
(a neutron and electron have about 1 amu while electrons have 0.000548 amu)
