independent variable: how much bread there is
dependant variable: temperature, location, time, size.
hypothesis, the one with the bread will be way more moist than the one without.
control group: no bread at all.
experimental group: brownies with bread
constants: same tupperware, placement, time, size.
Answer:
around 50–55 degrees.
Explanation:
I believe this would be it because chemical reactions haven't happened yet. This is the usual tempurature for tap water. :)
The answer is group 1A.
In the ionic compound formula X₂SO₄, SO₄ has a -2 charge. Hence to balance this -2 charge of SO₄, X must have a +1 charge.
Group 1A elements form X⁺ type of ions because they are metals. So, they have the tendency to lose electrons.
Hence, X must belong to the 1A group.
Ionic Compounds-
- Ionic compounds are formed by the electrostatic attraction between the anions and the cations.
- Cations are positively charged ions that are formed due to the loss of electrons.
- And the anions are negatively charged ions that are formed due to the gain of electrons.
- Due to this, they have opposite charges and form bonds known as Ionic Bond.
