Answer: Atoms that have lost or gained electrons and are now charged (different number of electrons). By putting the correct amount of protons and neutrons in the center, and you cannot have more than 2 protons/neutrons than the other if you want it to be stable. The number of protons determines the name of the element.
Answer:
A. Contain cells that connect to form pipes.
B. Transport water and food.
Explanation:
The vascular tissue is known to be conducting tissue which has more than one cell type. It is usually found in vascular plants. It is composed of xylem and phloem.
Their function is to transport fluid (like water) and other nutrients, therefore they have cells that connect to form pipes. The xylem and phloem occur together in vascular bundles in the plant organs passing through stems, leaves and roots.
Answer:
40 grams.
Explanation:
If 20 grams of C is formed from the combination or reaction of A and B chemicals in 10 minutes, 40 grams of C is formed in 20 minutes because the time is doubled so the concentration of C chemical is also doubled. If the time is increased further, more concentration of C chemical is produced until the amount of chemicals A and B are present. If we put an enzyme in the solution, the time of the reaction can be reduced.
Answer:
It goes the crust mantle outer core and inner core. The crust is what we are standing on it has dirt, rock, stone, the mantle it has lots of silicate rocks and magnesium. The outer core has liquid nickel and iron and the inner core has solid metals
Answer:
pH = 6.5
Explanation:
Given data:
pH of substance = ?
[OH⁻] concentration = 3.2×10⁻⁸
Solution:
pOH = -log[OH⁻]
pOH = -log[3.2×10⁻⁸]
pOH = 7.5
we know that,
pH + pOH = 14
pH = 14- pOH
pH = 14 - 7.5
pH = 6.5
