Answer:
Explanation:
according to the balance chemical equation
2 moles of c6h14 give us 14 moles of H2O
now mass(in gram) of 2 moles of C6H14 is
moles=mass/molar mass
mass=molar mass*moles
molar mass of C6H14 is 86 therefore
mass=86*2=172
now mass of 14 moles of water is
mass=molar mass*moles
molar mass of water is 18
mass=18*14=252
from the above calculations we conclude that
172 grams of C6H14 produce 252 grams of water
so 1.28 grams of C6H14 produce =252*1.28/172=1.87 grams of water
result is that 1.28 grams of C6H14 produced 1.87 grams of water
It would be neutron because protons have a positive charge, electrons are not in found in the nucleus of an atom, orbital doesn't have any thing to do with a nucleus of an atom, and a nucleus can't be found in a nucleus
<h3><u>Answer;</u></h3>
Adaptation
<h3><u>Explanation;</u></h3>
- Adaptation refers to the process in which animal or plant species becomes fitted to the environment. This occurs as a result of genetic changes or mutations.
- Adaptations may be, behavioral, psychological or structural. Behavioral adaptations are responses made by an organism which help it to survive.
- Psychological adaptations are body processes that helps and organism to survive or reproduce, while structural adaptations are features of the body of organisms which helps it survive or reproduce.

3.
Here underlined is
A. Brønsted-Lowry acid
B. Brønsted-Lowry base
C. Lewis acid
D. Lewis base
Answer: 1. Brønsted-Lowry acid
2. Lewis base
3. Brønsted-Lowry base
Explanation:
According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates protons and a base is defined as a substance which accepts protons.
According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.
1.
As is donating a proton , it acts as a bronsted acid.
2.
As contains a lone pair of electron on nitrogen , it can easily donate electrons to and act as lewi base.
3.
As is accepting a proton , it acts as a bronsted base.
The number of kilograms of fuel that are contained in one canister is 1.03 Kilograms
calculation
mass = density x volume
Density= 0.710 g/cm³
volume = 1.45 L
convert 1.45 l into cm³ to make the units uniform
that is 1 L= 1000 cm³
1.45 L= cm³
by cross multiplication
= (1.45 L x 1000 cm³) / 1 L = 1450 cm³
mass is therefore = 0.710g/cm³ x 1450 cm³ =1029.5 grams
convert grams to Kg
1 kg = 1000 grams
? kg =1029.5 grams
by cross multiplication
= (1 kg x 1029.5 grams) /1000 grams = 1.0295 Kg ≅1.03 kg
