Answer:
Ans => C => 43.3%
Explanation:
2CO + O₂ => 2CO₂
Given 1g CO = 1g/28g·mol⁻¹ = 0.036 mol CO
b/c coefficient of CO = coefficient of CO₂ => moles CO₂ = 0.036 mol = 0.036mol x 44g/mol = 1.57 gCO₂ (theoretical yield)
%Yield = (actual yield/theoretical yield) x 100% = (0.68g/1.57g) x 100% = 43.3%

Someone please answer this...
Answer:
5446.8 J
Explanation:
From the question given above, the following data were obtained:
Mass (M) = 50 g
Initial temperature (T₁) = 70 °C
Final temperature (T₂) = 192.4 °C
Specific heat capacity (C) = 0.89 J/gºC
Heat (Q) required =?
Next, we shall determine the change in the temperature. This can be obtained as follow:
Initial temperature (T₁) = 70 °C
Final temperature (T₂) = 192.4 °C
Change in temperature (ΔT) =?
ΔT = T₂ – T₁
ΔT = 192.4 – 70
ΔT = 122.4 °C
Finally, we shall determine the heat required to heat up the block of aluminum as follow:
Mass (M) = 50 g
Specific heat capacity (C) = 0.89 J/gºC
Change in temperature (ΔT) = 122.4 °C
Heat (Q) required =?
Q = MCΔT
Q = 50 × 0.89 × 122.4
Q = 5446.8 J
Thus, the heat required to heat up the block of aluminum is 5446.8 J

Answer:
36 oxygen atoms
Explanation:
From the question given above, the following data were obtained:
Compound => 4Al₂(CO₃)₃
Number of Oxygen atom in the compound =?
The number of oxygen atom in the above compound can be obtained as follow:
4Al₂(CO₃)₃
Al = 4 × 2 = 8 atoms
C = 4 × 3 × 1 = 12 atoms
O = 4 × 3 × 3 = 36 atoms
From the simple illustration made above, there are 36 oxygen atoms in the compound.
Carlita’s body is made up of many cells. What is one thing all her cells have in common?
Answer:
All of them have a nucleus..
Explanation:
Pretty simple stuff. There's no cell without one.
Carlita’s body is made up of many cells. The one thing that all her cells have in common is they have the same kind of genes.
What are genes?Genes are tiny pieces of spherical hereditary material that are bead-shaped and found on chromosomes. They hold the organism's genetic makeup. The number of genes on each chromosome is incalculable.
The hereditary material that makes up chromosomes is arranged in x shapes inside the nucleus. DNA, genes, and proteins make it up. An organism's genotype is distinct from other organisms because of its distinct genetic makeup, and this distinction can be passed down from one generation to the next.
Traits may be influenced by genes, the environment, or a mixture of the two. Quantitative features can also be qualitative, such as eye colour (such as height or blood pressure).
Therefore, numerous cells make up Carlita's body. Her cells all share the same type of genes, which is the only thing that unites them.

5) Chlorine has 7 valence electrons. Neon has 8 valence electrons. Which on is more likely to undergo a
chemical reaction, and why?
Answer:
well, chlorine will undergo in a chemical reaction
Explanation:
neon has completed valence shells, so it neither need electron and or it also don't need to donate the electrons. hence it will not participate in any chemical reaction and it is stable in nature.
whereas chlorine need one more electron to complete it's valence shell and in order to be stable , so it will try to gain one electron , hence
it will take place in a chemical reaction
Which circuit hook-up design will have the brightest light bulb?A - 1 battery 1 bulb, B - 2 batteries 1 bulb, C - 3 batteries one bulb, D 2 batteries the bulb is on the other end, E 1 battery and 1 bulb on the other end
Question 5 options:

Heres another for you guys!
Answer:
I believe it is E because the battery has a wire, a power source(the battery), and a bulb connected together thus making a full series circuit. Furthermore, the more batteries they are to a series circuit, the more dimmer the light bulbs will be.

How is a carbon atom different from a hydrogen atom?
Answer:
Carbon atom is a chemical element with the symbol C and atomic number 6 ( electrons). While Hydrogen atom is an atom of the chemical element hydrogen that have only 1 electron.
Explanation:
The carbon atom different from a hydrogen atom, because the atomic number of hydrogen is 1 . The atomic mass number of hydrogen is also one. For the carbon atom, the atomic number is 6, and the atomic mass number of carbon is 12.
What is an atomic number ?The term atomic number is defined as the number of a chemical element in the periodic system. The elements are arranged in order of increasing number of protons in the nucleus.
The atomic number is situated at the upper left, or number of protons. In the middle is the letter symbol for the element. Atomic number is equal to the proton number or the number of protons found in the nucleus of every atom of that element.
Thus, Carbon atom is a chemical element with the symbol C and atomic number 6. Whereas hydrogen atom is an atom of the chemical element hydrogen that have only 1 electron and its symbol is H.

. A skydiver jumps from an airplane and opens his parachute. At some point during his fall, the downward force of gravity on the skydiver is equal to the upward force of drag on the parachute. Which of the following best describes the skydiver's motion at this point? The skydiver is gaining speed downward. The skydiver is moving at a constant speed. The skydiver is decreasing in speed.
The upward drag and downward force is equal for the skydiver when he jumps down from the plane. Thus, he experiences a constant speed through out his motion.
What is gravitational force?Gravitational force is a kind of force by which a body attracts other objects into its center of mass. Force exerted by the body depends on the mass and distance to it.
Earth pull every objects into its surface by gravitational fore of attraction. For moving body the the gravitational force acting downward have an acceleration due to gravity.
The skydiver experiences a force upward by the drag of a the parachute. When this force becomes equal to the downward fore of gravity, then his speed will be constant thus, no gain or lose for speed.

Which kind of worm has a closed circulatory system?
a planarian
a fluke
a pinworm
an earthworm
An earthworm has a closed circulatory system.
The earthworm has a closed circulatory system. An earthworm circulates blood exclusively through vessels. There are three main vessels that supply the blood to organs within the earthworm.
As important as they are alive for distributing nutrients and organisms and decomposing matter, worms are also very important in the food chain. They provide a crucial protein-rich source of food for other important species like birds, hedgehogs and frogs.
They may live up to eight years, though one to two is more likely. Full size for an earthworm varies among species, ranging from less than half an inch long to nearly 10 feet.
