Answer:
Flowers play a crucial role in our lives; they have been used for generations to express the thoughts and feelings words cannot fully explain. Mother nature is the short term used to describe how nature gives life and nurture as a mother does for her children. As humans, we are part of mother nature's plan. We are also connected to plants and flowers, and some of the benefits have been passed to the next generation and will always be. We can control the air that we breathe, the aura around us, how we feel, and the things we attract in life. Other than only gifting your loved ones with flowers on special occasions, you can make the best and lasting impressions on your loved ones with a flower plant gift. This gesture shows that you understand how flowers are important in our life. To shed light on the importance of flowers in our life, here is a blog that will give five importance of flowers
Answer:
A Cake Baking
Explanation:
All of the other options are physical changes because you can always bring it bake to it's original state unlike a cake baking you can't separate the flour, sugar, and eggs as it was before.
Answer:
Explanation:
To find how many moles are in the sample, you first must calculate how much one mole of C2H5OH weighs.
2(mass of C) + 5(mass of H) + (mass of O) + (mass of H)
= 2(12.01) + 5(1.008) + (16.00) + (1.008) = 46.068 g/mol
So, now that we know what 1 mole weighs, we can simply divide the weight of the sample by the weight of a mole of ethanol to get our answer.
39.2 / 46.068 = approximately 0.851 mol of ethanol
The mass of carbon dioxide that would be made by reacting 30 grams C2H6 with 320 grams O2 will be 80 grams
From the balanced equation of the reaction:
The mole ratio of C2H6 to O2 is 2:7.
- Mole of 30 grams C2H6 = mass/molar mass
= 30/30
= 1 mole
- Mole of 320 grams O2 = 320/32
= 10 moles
Thus, C2H6 is the limiting reactant.
Mole ratio of C2H6 to CO2 according to the equation = 1:2
Since the mole of C2H6 is 1, the equivalent mole of CO2 would, therefore, be 2.
Mass of 2 moles CO2 = mole x molar mass
= 2 x 44
= 88 grams
