Explanation:
Unit 10 - Acid/Base ... (a) Mg(OH. 2. ) (b) Mg(OH). 2. (c) Mg. 2. OH. (d) MgOH. 2. Standard: ... balanced equation for these neutralization reactions: 3. HCl + NaOH → ... H2CO3 + Ca(OH)2 → ... C5.7B Predict products of an acid-base neutralization. 8. 2 NH4OH + H2S ...An Arrhenius base is a compound that increases the OH − ion concentration in ... and a base is called a neutralization reaction and can be represented as follows: ... chemical equation for the neutralization reaction between HCl and Mg(OH) 2. ... acid, an Arrhenius base, or neither. a) NaOH. b) C 2H 5OH. c) H 3PO 4. 6
It will become oxygen because carbons atomic number is 6 which means it has 6 protons so when you add 2 more protons you will have 8 all together and oxygens atomic number is 8 which is 8 protons
In fact, it should be a straight line but the curve is rarely straight when the concentrations are either to high or to low.
This is due to the accuracy of the spectrometer. If concentration is too low, the amount of light transmitted is near 100% of the incident light and the electronic device can not measure it precisely. In an opposite way then the concentration is too high, the amount of light transmitted is too low and can not be measured accurately. However Beer-lambert law holds.
Answer:
a) 24 g
b) 56.4 g
c) Físico.
d) Cambio de sólido a líquido.
Explanation:
Hola.
a) En este caso, dado que sabemos que el recipiente completo con agua pesa 56.4 g y vacío pesa 32.4 g, podemos calcular la masa de agua en el recipiente por medio de una resta:
b) Aquí, no es necesario calcular nada, ya que la masa de agua líquida que se congela es la misma de hielo formada, por tanto el recipiente con el hielo tendrá la misma masa de 56.4 g.
c) Aquí, dado que el agua cambia solamente de estado, sigue siendo agua, por tanto dicho proceso es físico.
d) La fusión, la definimos como un proceso físico en el que una sustancia en estado sólido cambia a estado líquido a partir de la adición de energía térmica que permite la separación de las moléculas hacia el estado líquido.
