Ok so i was writing a big àss explanation but i realized im not that good at explaining as i thought i was so plz just watch these vids by tyler dewitt. my awesome teacher recommended these videos and tyler dewitt's also a really good teacher and if you watch his vids you'll really master this topic:

Writing Ionic Formula: https://youtu.be/URc75hoKGLY

Naming Ionic Compounds: https://youtu.be/mKo72RnN37E

Writing Formulas with Polyatomic Ions: https://youtu.be/p9iQ5Qn42DM

Writing Ionic Formulas with Transition Metals: https://youtu.be/H4nfE8gRX7Q

Naming Ionic Compounds with Transition Metals Introduction: https://youtu.be/H4nfE8gRX7Q

*btw the pic i attached will be very useful to you except when youre dealing with transition metals and also these links will also help you. the professor dave explains videos about naming ionic compounds just didnt help me but tyler dewitt really did so if you watch his videos you'll be fine

A molecule that closely resembles the shape of a substrate and therefore also fits into the active site of an enzyme might serve
Fynjy0 [20]

Answer: inhibitor

Explanation:

Enzymes have a shape that closely resemble that of the substrate hence they fit into the substrate by lock and key mechanism. The activity of the enzyme hinges on its similarity with the substrate in shape. Any other molecule similar to the shape of the substrate can fit into the substrate thereby preventing the enzyme from locking with the substrate. Such substances are called inhibitors. They decrease the activity of an enzyme.

If you start with 100 grams of hydrogen-3, how many grams will you have after 24.6 years?
svet-max [94.6K]

Answer:

The mass left after 24.6 years is 25.0563 grams

Explanation:

The given parameters are;

The mass of the hydrogen-3 = 100 grams

The half life of hydrogen-3 which is also known as = 12.32 years

The formula for calculating half-life is given as follows;

N(t) = N_0 \times \left (\dfrac{1}{2} \right )^{\dfrac{t}{t_{\frac{1}{2} }} }

Where;

N(t) = The mass left after t years

N₀ =  The initial mass of the hydrogen-3 = 100 g

t = Time duration of the decay = 24.6 years

t_{\frac{1}{2} } = Half-life = 12.32 years

N(24.6) = 100 \times \left (\dfrac{1}{2} \right )^{\dfrac{24.6}{12.32}} } = 25.0563

The mass left after 24.6 years = 25.0563 grams.
