Dinner including grilled chicken,roasted brussels sprouts and cooked quinoa have all main nutrients and are low in carbohydrates.
What are carbohydrates?
A carbohydrate is defined as a bio-molecule which consists of carbon,hydrogen and oxygen atoms which are usually in the ratio of 2:1 with the empirical formula C[tex]_n[/tex](H₂O)[tex]_n[/tex].
This term is most commonly used in biochemistry as a synonym of saccharide which is a group of sugars, starch and cellulose.
They perform various functions in living organisms. They serve as an energy source and as well as structural components . They are a key component in providing nutrition and are found in wide variety of natural as well as processed foods.
Carbohydrates occur as cellulose in the cell walls of plants and is one of the components of insoluble dietary fibers.

How many liters of oxygen are needed to burn 2.76 L of carbon monoxide?
Answer: 1,38 litres
Explanation: it should be 2 CO + O2 ⇒ 2 CO2
In Same temperature volumes are proportional
To amounts of substances. So amount of Oxygen is half of
Amount of CO
Answer: 1.38 L O2
Explanation:
2CO + O2 = 2CO2
So,
1 mole CO = 22.4 L CO
2 mole CO = (22.4 ×2)L CO
= 44.8 L CO
And 1 mole O2 = 22.4 L O2
44.8LCO are burned by 22.4LO2 1 L CO are burned by 22.4÷ 44.8
= 0.5 L O2
2.76L CO are burned by0.5×2.76
= 1.38 L O2
So, 1.38 L O2 are needed to burn
2.76 L CO

how much is the mass of a man if
he has to do 2500 joules of work in
climbing a tree 5 meters tall
Answer:
50kg
Explanation:
Using the formula for potential energy, which is the amount of energy due to position;
P.E = m × g × h
Where;
m = mass (kg)
g = acceleration due to gravity (10m/s²)
h = height (metres)
According to the information provided in this question, m = ?, P.E = 2500J, h = 5m
Using P.E = m × g × h
m = P.E/gh
m = 2500/(5 × 10)
m = 2500/50
m = 50kg
The mass of the man is 50kg.

Calculate: A. Mercury has a specific Heat Capacity of 0.14 J/goC. How much heat is needed to raise the thermometer temperature 15 oC to 95 oC. There is 5 g of mercury in the thermometer.
Answer:
[tex]\boxed {\boxed {\sf 56 \ Joules}}[/tex]
Explanation:
We are given the mass, specific heat, and temperature, so we must use this formula for heat energy.
[tex]q=mc \Delta T[/tex]
The mass is 5 grams, the specific heat capacity is 0.14 Joules per gram degree Celsius. Let's find the change in temperature.
ΔT= final temperature - initial temperature ΔT= 95°C - 15°C = 80°CWe know the variables and can substitute them into the formula.
[tex]m= 5 \ g \\c= 0.14 \ J/ g \ \textdegree C \\\Delta T= 80 \ \textdegree C[/tex]
[tex]q= (5 \ g )( 0.14 \ J/ g \ \textdegree C ) ( 80 \ \textdegree C)[/tex]
Multiply the first numbers. The grams will cancel.
[tex]q= 0.7 \ J/ \textdegree C(80 \ \textdegree C )[/tex]
Multiply again. This time the degrees Celsius cancel.
[tex]q= 56 \ J[/tex]
56 Joules of heat are needed.

2 CH3Oh + 3O2 + 2CO2 + 4 H2O how many liters of carbon dioxide will be formed form 6 moles of oxygen
Answer:
89.6 L of CO₂
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
2CH₃OH + 3O₂ —> 2CO₂ + 4H₂O
From the balanced equation above,
3 moles of O₂ reacted to produce 2 moles CO₂.
Next, we shall determine the number of mole CO₂ produced by the reaction of 6 moles of O₂. This can be obtained as follow:
From the balanced equation above,
3 moles of O₂ reacted to produce 2 moles CO₂.
Therefore, 6 moles of O₂ will react to produce = (6 × 2)/3 = 4 moles CO₂.
Thus, 4 moles CO₂ were obtained from the reaction.
Finally, we shall determine the volume occupied by 4 moles CO₂. This can be obtained as follow:
1 mole of CO₂ occupied 22.4 L.
Therefore, 4 moles CO₂ will occupy = 4 × 22.4 = 89.6 L
Thus, 89.6 L of CO₂ were obtained from the reaction.

Which example describes how the water cycle carries on energy transfer? a flooding river depositing silt on a floodplain a warm ocean current warming the air above it ocean water depositing sand particles on a shore water seeping through the soil and dissolving salts
Answer:
The water cycle is driven primarily by the energy from the sun. This solar energy drives the cycle by evaporating water from the oceans, lakes, rivers, and even the soil. Other water moves from plants to the atmosphere through the process of transpiration.
In an ecosystem, the water cycle carrying on energy transfer is best exhibited the example of a warm ocean current warming the air above it .
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Which molecule would diffuse faster So, or SO,? Explain your reasoning.
The given question is incomplete. The complete question is:
Which molecule would diffuse faster [tex]SO_2[/tex], or [tex]SO_3[/tex],? Explain your reasoning.
Answer: [tex]SO_2[/tex] will diffuse faster as it has low molecuklar weight.
Explanation:
From Graham's law of diffusion rates, the rate of diffusion of a gas is inversely proportional to the square root of its molar mass.
[tex]Rate\propto \sqrt\frac{1}{M}[/tex]
or [tex]\frac{Rate_1}{Rate_2}\propto \sqrt\frac{M_2}{M_1}[/tex]
Molecular mass of [tex]SO_2[/tex] is 64 g/mol and Molecular mass of [tex]SO_3[/tex] is 80 g/mol
Thus as molecular mass of is less , it will diffuse faster.
