Answer:
Meteorites are consensually considered to be involved in the origin of life on this Planet for several functions and at different levels: (i) as providers of impact energy during their passage through the atmosphere; (ii) as agents of geodynamics, intended both as starters of the Earth’s tectonics and as activators of local hydrothermal systems upon their fall; (iii) as sources of organic materials, at varying levels of limited complexity; and (iv) as catalysts.
Explanation:
Thermal energy will flow from an object high temperature to an object of low one. In this case, the thermal energy will flow from object B to object A.
Answer:
1. 3.56 M.
2. 0.99 M.
Explanation:
¡Hola!
1. En este caso, dado que la molaridad de una solution es calculada por medio de la siguiente ecuación:

Es posible calcular la molaridad de 50 gramos de hidróxido de potasio primero calculando las moles en dicha masa por medio de la masa molar:

Luego, dado el volumen de la solución, podemos calcular la molaridad:

2. En este segundo ejercicio, procedemos de la misma manera, pues primero calculamos las moles de nitrato de potasio:

Luego, calculamos la molaridad justo como se hizo anteriormente:

Best regards!
Answer: 0.123 M
Explanation:
According to the neutralization law:

where,
= molarity of
solution = ?
= volume of
solution = 15.00 ml
= molarity of
solution = 0.100 M
= volume of
solution = 18.44 ml
= valency of
= 1
= valency of
= 1


Therefore, the concentration of the unknown HBr solution is 0.123 M
