tigry1 [53]

Sugar burns and turns black. A completely new substance was formed, which is the main pointer for it being a chemical reaction. More evidence would be change of color, odor, and the fact that flammability is a chemical property so setting something on fire would be a chemical change.

Answer:

160.000 años corresponde a 16.000 décadas.

Explanation:

Para resolver correctamente el ejercicio debemos plantear la regla de tres simple de la siguiente manera:

1 década equivale a 10 años; A cuantas decadas equivalen 160.000 años?

1 década→10 años

x ←160.000 años

Debemos multiplicar 160.000 por 1 y luego dividir entre 10 ;

x=( $\frac{160.000x1}{10}$ )=16.000 décadas; en notación científica sería 16x10^3.

Respuesta: 160.000 años corresponde a 16.000 décadas.

Shaun's doctor has recommended that he consume 200 calories of protein a day. Shaun consumed 176 calories of protein in one day.

evablogger [386]

Answer: Shaun must consume 6 more g of protein to reach the required amount.

Explanation:

Given : Recommended amount of protein = 200 calories

Now 4 calories = 1 gram of protein

Thus 200 calories = $\frac{1}{4}\times 200=50$ g of protein.

Calories consumed per day by Shaun = 176 calories

176 calories = $\frac{1}{4}\times 176=44$ g of protein.

Thus Shaun need to consume = (50-44) g = 6 of protein to reach the required amount.

Shaun must consume 6 more g of protein to reach the required amount.
