Answer:
4 C2H5 + 13 O2 -> 8 CO2 + 10 H2O
Explanation:
What I do is I make a chart of how many elements the product side and reactant sides have:
Reactants-
2 C
5 H
2 O
Products-
1 C
3 O
2 H
It's easier to see how many coefficients are needed for the reaction to be balanced then. Hope this helped.
Answer:
H2Br + 2KOH ----- K2Br + 2H2O
Answer:
The greenhouse effect
Explanation:
The greenhouse effect is a straightforward method that heats the Earth's exterior. When the Sun's rays touch the Earth's environment, some of it is bounced back to space and the rest is grasped and re-heated by greenhouse gases. The consumed energy heats the environment and the exterior of the Earth.
Answer:
The answer is
<h2>0.34 cm³</h2>
Explanation:
The denisty of a substance can be found by using the formula
<h3>
</h3>
Making volume the subject we have
<h3>
</h3>
From the question
mass = 4.62 g
Density = 13.5 g/cm³
Substitute the values into the above formula and solve for the volume
That's
<h3>
</h3>
= 0.34222……
We have the final answer as
<h3>0.34 cm³</h3>
Hope this helps you
Answer:
(1) The outermost shell should have Eight electrons to complete or called as octet and attain stability.
(2) Hydrogen and Chlorine share Electrons with each other and form Covalent bonding.
(3) Hydrogen forms an octet by obtaining an electron, and Helium is the only element that has an octet with two electrons.
(4) The octet rule states that an atom should attain eight electrons in the outermost shell to get stability, However we have exceptional like Hydrogen and helium.
(5) In Ionic bond there is a formation of Ions of the elements in a compound, like in NaCl there will be Na+ and Cl-.
(6) While in Covalent bond there is sharing of electron between the atoms included like O2.
(7) In ionic bond there is an electrostatic force of attraction while in Covalent bond the is a mutual sharing of electrons.
