The little dipper is located in Ursa Minor you would also get a clue because... Minor and little
Well February 29 is a date that usually occurs every 4 years and this is called a leap year.This day is added to the your calendar in leaps years as a corrective measure because the Earth does not orbit the sun in precisely 365 days! hope it helps and have a great day!
Answer:
For example, 20mL of stock solution with 80mL of water.
Explanation:
60g of NaOH in 0,300L have a molar concentration of:
60g NaOH × ( 1 mol / 40g) = 1,5 moles of NaOH / 0,300L = 5M
If you want to mix this solution with water to produce a 1M NaOH solution you need to mix 1 part of volume of the stock solution per 5 parts of total volume. For example, mix 20mL of stock solution with 80mL of water. That is:
5M NaOH × ( 20mL stock solution / 20mL + 80mL -Total volume-) = 1M NaOH solution
I hope it helps!
An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors include plants, animals, and other organism .
(A) Color changes from reactant to products.
The rate of a chemical reaction is calculated by dividing the rate of change in a reactant or product's concentration by the coefficient from the equation's balanced state.
2N2O5(g) → 4NO2(G) + O2(g)
A change in color and the appearance of bubbles are two indications of a chemical shift.In a chemical process, the makeup of the components changes; in a physical change, the appearance, smell, or straightforward exhibition of a sample of matter changes without changing its composition.
Despite the fact that we refer to them as physical "reactions," nothing is actually changing. A change in the substance in question's elemental composition is necessary for a reaction to occur. Therefore, from now on, we will simply refer to bodily "reactions" as physical changes.
Physical modifications must only cause a variation in display without altering the composition. Typical modifications include, but are not limited to:
Texture\Color\Temperature\Shape
