Answer:
70 kg = 7e+7
Explanation:
multiply the mass value by 1e+6
Dissolving can separate the three. Because pepper doesn't mix with water and neither do pebbles.
Answer:
Energy production requires the setting up of a complete interconnected chain from generation of energy from the root source of the energy to the storage of the generated energy and the eventual utilization of the energy when required
Solar energy, indirectly, continues to be the main source of energy, however, the direct use of solar energy to power the systems we use in our everyday life, require the development of technologies, such as high efficiency solar cells, means of energy storage, and compatible efficient energy usage which are industrial areas that are seeing good progress but in which the current developed equipment are expensive to produce, and due to their efficiency, are undergoing further research and development
Therefore, due to the continuous increasing improvement in solar technology which can observed, the use of the produced energy through solar is evolving, and therefore, will continue to play a continuously increasing but lower role compared to other sources of energy which have been developed to satisfactory level that can drive an industry, considering the financial investment involved
Explanation:
Answer:
Some atoms do not have a proton.
Protons have about same mass as electrons.
Protons have the magnitude of charge as neutrons, but are opposite in sign.
Explanation:
Protons are the positive charge particles which are present inside the nucleus and has a mass equal to neutron.
an atom has equal number of electrons and protons hence it is not possible that atom is found in a state where is does not have any proton.
The mass of proton is equal to that of neutron but not electron. Protons are heavier than that of electrons.
Protons are the positively charged particles whereas neutrons do not have any charge present in it.
Hence the selected three options about protons are false.
Ba(NO₃)₂ + Na₂SO₄ → BaSO₄ + NaNO₃
By Trial and error.
Ba(NO₃)₂ + Na₂SO₄ → BaSO₄ + 2NaNO₃
Check:
LHS RHS
Ba 1 1
N 2 2
S 1 1
O 3*2 + 4 = 10 4 + 2*3 = 10
