Las principales funciones del sistema nervioso es recibir información del entorno externo y produce respuestas a la información recibida. El sistema nervioso comprende el cerebro y la médula espinal que controla todo el cuerpo. hay células sensoriales presentes en la piel que reciben estímulos externos y a través de las neuronas la información se transfiere al sistema nervioso. después de procesar la información, la respuesta se envía a los músculos para que actúen frente a los estímulos externos.

The procedure for a reaction directs you to use 0.057 mol of the liquid ester, methyl benzoate (M.W. 136.15, d 1.094 g/mL), in y

lesantik [10]

Answer:

7.1 mL

Explanation:

Step 1: Given data

Moles of methyl benzoate (n): 0.057 mol

Molar mass of methyl benzoate (M): 136.15 g/mol

Density of methyl benzoate (ρ): 1.094 g/mL

Step 2: Calculate the mass corresponding to 0.057 moles of methyl benzoate

We will use the following expression.

m = n × M = 0.057 mol × 136.15 g/mol = 7.8 g

Step 3: Calculate the volume corresponding to 7.8 g of methyl benzoate

We will use the density formula.

ρ = m/V

V = m/ρ

V = 7.8 g/1.094 g/mL

V = 7.1 mL

What is this?(−2h+9)(9h−2)=

OLga [1]

The answer you're looking for is "-18h^2 + 85h - 18".

This can be found by distributing "9h" into "(-2h + 9). This should give you "-18h^2 + 81h". Then youd distribute "-2" into the same parenthesis, which will give you "4h - 18".

Together, you would have "-18h^2 + 81h + 4h - 18". Combine like terms (81h and 4h), and you'll get the answer of "-18h^2 + 85h - 18".

I hope this helps!!
