Answers

Answer 1

Answer: Use Socratic for helps

Answer 2

Answer: Physical properties. O; one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom. Water is a tasteless, odorless liquid at ambient temperature and pressure. Liquid water has weak absorption bands at wavelengths of around 750 nm which cause it to appear to have a blue colour.

1.986 x 10negative exponent 6 or 1.986 x 10^6

Answers

Answer:

$0.000001986$

Explanation:

We have the number $1.986*10^(-6)$ . Standard notation would basically be this number without the $10^(-6)$ part.

To get rid of this part, we need to move the decimal point 6 places to the left (we go left because it's negative 6, indicating division).

So, when we move the decimal point 6 places to the left, the resulting number is: $0.000001986$ , with 5 zeros after the decimal point before a nonzero number.

Thus, the answer is $0.000001986$ .

helium gas in a 2.00 L cylinder is under 1.12 atm pressure. At 36.5°C that same gas sample has a pressure of 2.56 atm. What was the initial temperature of the gas in the cylinder?

Answers

Answer:

T₁ = 135.41 K

Explanation:

Given data:

Initial pressure = 1.12 atm

Finial temperature = 36.5 °C (36.5 +273 = 309.5 K)

Initial temperature = ?

Final pressure = 2.56 atm

Formula:

P₁/T₁ = P₂/T₂

P₁ = Initial pressure

T₁ = Initial temperature

P₂ = Final pressure

T₂ = Final temperature

Solution:

P₁/T₁ = P₂/T₂

T₁ = P₁T₂ /P₂

T₁ = 1.12 atm × 309.5 K / 2.56 atm

T₁ = 346.64 atm . K / 2.56 atm

T₁ = 135.41 K

On Sunday NASA's SpaceX launched 4 astronauts into space for a mission lasting 5 months. They named their spacecraft RESILIENCE.In 4-6 sentences explain what the word RESILIENCE means to you. Also, why do you think they named their spacecraft that? Please respond to this prompt in your own words, there is no need to google!

!!DO NOT GOOGLE IT!!

Answers

Answer: I think they named it RESILIENCE to point out that it should be resilient to harsh conditions and that it would be able to push through with little damage. when I hear the word resilience I think of strong able to push through. I think of myself of resilient because _________________. Naming the space craft RESILIENCE is smart because the astronauts will know they are safe when they launch.
