docker41 [41]

Answer:

Considere uma molécula de glicose (C6H12O6) e indique: a-) O número de átomos de carbono = 6 b-) O número de átomos de hidrogênio = 12 c-) O número de átomos de oxigênio = 6d-) Quantos átomos teremos quando descubro se temos 8 moléculas dessa substância?

  48 oxigênio, 48 carbono e 96 hidrogênio e-) Quantos átomos de cada elemento teremos com 20 moléculas de glicose?

160 de oxigênio e carbono e 240 de hidrogênio.

Explanation:

A glicose é uma das moléculas mais usadas no organismo humano, pois é uma molécula em que sua decomposição é muito mais fácil que os aminoácidos, portanto, eles produzem como produto a moeda de energia que é ATP mais facilmente do que outros alimentos .

A glicose não é encontrada apenas em alimentos açucarados, isso é um mito, na verdade é a unidade de carboidratos (de assados ​​a doces)

1.40 m3 is how many mL
Zarrin [17]

\LARGE{ \boxed{ \rm{ \pink{Solution:}}}}

We know, 1 m³ of space can hold 1000 l of the substance.

⇛ 1 m³ = 1000 l----(1)

And, 1 l is 1000 times more than 1 ml

⇛ 1 l = 1000 ml------(2)

So, From (1) and (2),

⇛ 1 m³ = 1000 × 1000 ml

⇛ 1m³ = 1000000 ml

We had to find,

⇛ 1.40 m³ = 1.40 × 1000000 ml

⇛ 1.40 m³ = 140/100 × 1000000 ml

⇛ 1.40 m³ = 1400000 ml

⇛ 1.40 m³ = 14,00,000 ml / 14 × 10⁵ ml / 1.4 × 10⁶ ml

☃️ <u>So</u><u>,</u><u> </u><u>1.40</u><u> </u><u>m</u><u>³</u><u> </u><u>=</u><u> </u><u>1</u><u>4</u><u> </u><u>×</u><u> </u><u>1</u><u>0</u><u>⁵</u><u> </u><u>m</u><u>l</u><u> </u><u>/</u><u> </u><u>1.4</u><u> </u><u>×</u><u> </u><u>10</u><u>⁶</u><u> </u><u>ml</u><u>.</u>

How much energy will a sample of copper alloy ( 63.0 g) lose if it is cooled from 48.0° to 23.0°C ?
Ymorist [56]

Answer:

Heat lost would be 606.375J

Explanation:

Mass = 63.0g

T1 = 48°C

T2 = 23°C

Specific heat capacity of copper (c) = 0.385J/g°C

Q = Mc∇T

Q = Mc(T₂ - T₁)

Q = 63 * 0.385 * (23 - 48)

Q = 24.255 * -25

Q = -606.375J

The heat lost would be 606.375J
