To satisfy the law of conservation of mass
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
Protons and neutrons are in the center of the atom, making up the nucleus. Electrons surround the nucleus. Protons have a positive charge.
Each element has a specific mass number and a specific atomic number. These two numbers are fixed for an element. The mass number tells us the number (the sum of nucleons) of protons and neutrons in the nucleus of an atom. it has mass number 235 , it means that the sum of neutrons and protons in a carbon atom is 235.3
Explanation:
It is known that when pH of a substance is more than 7 then the substance is considered basic in nature. When pH of a substance is less than 7 then the substance is considered acidic in nature.
And, when the pH of a substance is equal to 7 then it is considered neutral in nature.
The pH of given substances are as follows.
Coffee = 5.0
Orange Juice = 3.5
Milk = 6.5
Soda pop = 2.5
Battery acid = 1.0
As battery acid as very low pH therefore, it is highly acidic in nature.
Thus, we can conclude that given acids are arranged in increasing order of acidity as follows.
Milk < Coffee < Orange juice < Soda pop < Battery acid
Answer:
The answer is "Upland sandpipers are primary and secondary consumers because they eat grasses and grasshoppers".
Explanation:
The limited farmland nutrition web, that reveals better which Upland sandpipers were main and secondary customers in this farmland since they eat grass with grasshoppers.
- It also eat butterflies, bricks, shrimps, mollusks, worms, and nematodes, throughout contrast to bugs, which sandpipe gathers seed of hay, plants, conifers, and rice, rye, or strawberries.
- Highlands dragonflies sometimes assemble in recently burnt fields with such a wealth of squirrels.
The temperature of the 1 kg water will be lower.
Q=mcΔt
Q1= 1kg*c*Δt(1)
Q2= 2kg*c*Δt(2)
Q1=Q2
1kg*c*Δt(1) = 2kg*c*Δt(2)
Δt(1) = 2Δt(2)
We can see that change in temperature for 1 kg will be 2 times more that change in temperature for 2 kg of water.
